I’ve tried to provide you with as much information as possible about mistakes to avoid when you are interviewing. Mastering these elements can ensure your success when interviewing and make you more likely to get the job.

Here are 21 pieces of career advice no one ever gives you from well-known career advice expert and legal recruiter Harrison Barnes.

Understanding what you do for a living is very important for your career. You should understand the generality of your specific profession. You and your career are a product. You need to know where and how to market yourself in the best way possible. You need to be relevant and understand the skills you are offering. Being a relevant product is essential for your success. It’s easy to be relevant when you understand what you are doing and what purpose you serve. Being relevant is more than just getting a job. Being relevant also relates to serving the employers with the skills they need. You need to understand your market and what your customers want. This is the way to stay employed, and it is also the means to continual improvement.

Rumors are extremely dangerous. Competitors and colleagues alike share incorrect, negative information about you, these rumors can spread like wildfire and quickly shipwreck your career. Make sure that your peers know and understand you, show courtesy and respect for others, and avoid all types of arrogance; if you can do these things, you can mitigate the likelihood and potential damage of rumors.

The answers to these seven questions are essentially the same as your response to “Tell me about yourself.” You need to see yourself and your answer to every question from the employer’s point of view. Interviewers are looking for the best long-term fit for each job. Anything you say that supports this is likely to get you hired and anything that does not is likely to mean you will still be looking for a job.

Employees’ level of success and overall happiness has more to do with a particular culture (which is sometimes also referred to as the personality of an organization) than with any other factor. This article discusses (a) the importance of organizational...

Many people have a single weakness that they have failed to address, which holds them back in their careers and leads to job hopping. Job hopping indicates that something is wrong with a person’s attitudes and outlook rather than with their employers. Identify and fix the things that are holding you back rather than leaving your position when you should not, and much more success and happiness will come to you.

Rely on facts and statistics rather than opinions; when you depend on mere opinions, you inevitably face disastrous consequences. You must understand the difference between facts and opinions, analyze both, and adopt the former while disregarding the latter to make productive decisions.

In this article Harrison explains the economic rule which says – your rewards will be in direct proportion to the value you provide. In your career if you are not providing enough value, the rule will catch up with you sooner or later. In contrast, if you are providing more value than you receive you will probably have a very good career. Companies that provide more value than they receive for their products generally end up flourishing. Companies that provide very little value generally end up going out of business. The law of economics that is always operating in the background is that you always need to give more than you take and be prepared to give.

You need not only to fit in, but to be seen as fitting in with your coworkers. Harmonizing with your work environment is one of the most important things you can do for your career, and failing to do so can cause you serious problems. Achieving such harmony, however, will ultimately bring you closer to your career goals, and is among the primary things that society demands of its participants.

You must find a job about which you are passionate, perform it with dedication, and make sure this dedication is visible to those around you. When you devote yourself to a job that you love, you open the doors for greater happiness and fulfillment in your career and life. Employers and colleagues notice those who demonstrate passion for their jobs; they naturally gravitate towards these types of people, and avoid those who take a more perfunctory approach to their work.

In this article Harrison discusses what a good hiring manager should look for. Many people who make hiring decisions really do not know what they are doing. In fact, they often make mistakes when hiring. They put too much emphasis on skills and experience. But the single most important aspect of hiring is evaluating the person’s unique outlook on the world. If the person does not have a positive outlook on the world, he/she will bring down the morale of the other workers. The person will harm the company through the negative outlook. The key to success is having the power to stick it out in jobs and finding happiness wherever you are. Hiring people who do good work and are always able to find happiness should be the number one objective of hiring managers.

Everyone seeks to imitate the people they look up to, and with transference they believe that they have an understanding of other peoples’ thoughts, motives, and beliefs. Transference, however, can blind yourself to the true nature of those around you and can lead you to make wrong judgments or assumptions. You will be much more successful with a better understanding of who you are and how your perceptions of the world help or hinder you.

In this article Harrison discusses how your career can see growth if you choose to work with an employer who is marching forward. All employers go through different stages, and when you get in will have a real bearing on what happens to your career over time. The best time to get in is at the beginning of the growth cycle. The employer marching forward will provide you with the most important opportunities and the best overall career. The employers marching forward are easy to spot as they tend to be hiring more and more people. Such employers are excited about the future and the people working with them typically feel the same way. In your search for a job, and in choosing between employers, you need to find an organization that is marching forward or beginning a march.

Everyone has a distinct nature and view of the world; you must understand yours, and choose a lifestyle and work that matches your outlook. Jobs and coworkers who do not match your nature, acting outside of your nature, or trying to be something that you are not will only leave you unhappy. Your nature will likely never change regardless of outside conditioning, so you will achieve your greatest success in a job that you love.

Your ability to help people will determine the extent of your success; the more powerful and effective your help, the greater rewards you will receive. One of the rarest and most profound achievements is to follow through on your goals and create a paradigm-shifting idea. The more revolutionary your work, the more people you will affect and the more memorable of a career you will have.

Salesmanship is one of the most important skills you can have in your job hunt. You can use personality as a means of standing out and selling yourself, making sure that it comes through in everything you are doing. By injecting personality into your job search, you will soon notice changes in your life and career. People with personality succeed in sales because they draw attention; employers want to hire people with personalities, and a good personality can be your best job hunting tool.

Narcissistic Entitlement Syndrome (NES) afflicts many people in the current job market; they see themselves as special, and deserving of whatever they want at the expense of others. NES puts these people on a collision course with failure. Even if they do not themselves fail, colleagues with NES can negatively affect you; avoid NES and people afflicted with it at all costs.

Rather than adopt a victim mentality, work to take advantage of the opportunities that you already have. Most people only seek to gain as much as they can from their employers, hoping to get something for nothing by feigning victimhood. These people have no interest in being contributors, and refuse to take responsibility for their lives. Do not expect a free ride, but instead strive to perform at your greatest possible potential.

In this article Harrison discusses the importance of focusing entirely on your employer’s needs in order to succeed in your job and job search. A relationship with an employer is quite similar to any other relationship. In maintaining any relationship, you need to understand the other person’s needs. You need to concentrate more on giving than taking. Likewise, at work, you need to be more focused on your employer’s interests than your own. When you are applying for jobs and interviewing, you need to put yourself in the employer’s shoes. This will take you places and will give you the level of satisfaction you want out of your work relationship.

In this article, Harrison explains how the company you keep will inevitably be a major cause of success or failure in your career and life. Wrong associations can be harmful and although you cannot really avoid it all the time, you need to distance yourself from it. Unethical people can repeatedly injure your progress and you need to be aware of and understand the people you deal with, to protect yourself from those who could taint you and drag you down.

You need to stay focused on your work – and only your work – in order to achieve the results that you want. Bring passion to your work, and surround yourself with similarly passionate colleagues. Your coworkers may resent you without this passion. Employers care about how much you care about them and what you can do for them rather than how much money you hope to make. When you offer employers a tremendous value, you will be compensated accordingly.

It is importantly that you be totally and completely involved in your work. When you do this, you establish a flow where time and problems disappear, and you will find yourself completing tasks with very little effort. Upon entering a state of flow, you can do your work unconcerned with power, competition, or recognition, vastly improving your chances of success. Satisfaction and rewards come when you are one with your work.

Employers sometimes ask in the course of an interview about other interview you may have had, and how you handle this question can determine your success. You must convince your current interviewing employer that their position is your first choice before divulging any information about other interviews, and be careful how you justify your other interview to your prospective employer. You must convince your current interviewing employer that you consider their position to be your best fit, and would most help you meet your career goals of upward mobility.

A recommendation from a powerful person can make a huge difference in your job search; a reference from an influential person makes a tremendous difference to a prospective employer, and thus can be a major advantage for you. When an important person whom the company trusts recommends you, you instantly qualify for positions that may previously have been unattainable. Make the absolute most of your connections with the powerful people in your life, because doing so can instantaneously change your career and life.

Focus on what you are doing, not what others around you are doing. There are people to take action towards their goals, and then there people who sit on the sidelines and comment on the first group of people. People who are mostly interested in gossip and watching others usually lack the confidence and determination to take action themselves. The most successful people go account and accomplish things rather than sit back and watch others make things happen.

It is important to have a career that makes you happy, rather than pursuing a career simply because you or others think that you should. Life too short not to be doing the things that you really want to do with your life. If you do not yet know the kind of work that makes you genuinely happy, you need to go and find it.

In this article Harrison discusses the importance of putting your efforts in the right direction. The most important decision you can make is deciding where you are going to put your effort. If you choose the right field for your efforts, you will frequently be richly rewarded (even if you do not have a lot of skill in the field). When you identify something that the market wants, and provide it, then you can frequently do quite well—even if you are not particularly skilled. It is just a question of being at the right place at the right time and taking action. In your career, very little is more important than where you choose to focus your effort. Nothing is more important than working somewhere with opportunity and where you are being carried away by the wind of a positive economic current.

In this article Harrison discusses why emotional connections are so important in the workplace. In virtually every company, there are people who are not needed at all but are kept in the jobs due to some emotional connection. In every industry when layoffs occur, generally the first to go are those who do not have an emotional connection to the organization. According to Harrison there is a huge value attached to having emotional connections in your job. The holiday party, invitations to spend time with your boss outside of work, and other similar occasions are extremely important because they are a chance to form an emotional connection with the people you are working with. The emotional connection will take you farther and will last longer than any other sort of connection.

In this article Harrison discusses the importance of loving your work and also the people who give you work. Work is the most important thing you can have. Without work, everything stops. So respect the work you are doing. Having work is a privilege and this work can lead to more work. You need to respect people who give you work and you need to get work at all costs. It is never good to be without work. Being without work means your skills and value do not currently have a place. Do the work to the best of your ability. The only way to advance is by doing good work and exceeding expectations. Doing good work is crucial to our lives. Make the most of your job and give it your all. The harder you work, the higher you will climb.

You can change almost every aspect of your life through good negotiation. You must view your career in terms of opportunities to negotiate the best possible outcome; when you do this and hone your negotiation skills, you will achieve far more wealth, security, and happiness than would be possible for those who do not negotiate. While negotiation is critical, it must not be overdone; simply realize that there are always more potential opportunities than what might initially be on offer.

Companies who have been around for long periods of time are usually doing something right, and people who remain with a single employer for long periods are usually considered stable and committed to their jobs. Concern yourself with doing the best job possible and look for reasons to like your organization, and you will find that the organization will welcome you and foster your long-term success.

In this article Harrison discusses the importance of having open lines of communication. According to him this will consistently keep you employed. You need to be friends with everyone you meet in business and stop competing and seeing differences. You need to understand that you have no opponents. Your success will largely be determined by your ability to go into the world, find commonality and make friends with the people around you. You must abolish from your mind the idea that the people you are dealing with in your career and in business are your competition. You must get rid of the thought of competition. Be friendly with everyone you meet. Stop looking for differences, and do everything within your power to find affinity with other people. This will change your career permanently.

Get your employer to commit to you, and keep coming back again and again. This “lock in” is a tactic that companies use all the time, and one that you must practice to get and keep jobs. Make an offer to attract an employer, and then make yourself indispensable. People who fail to lock in their employers are usually the ones who find themselves laid off.

Proof is itself a tool in your job search and if you employ it effectively, you will stand ahead of your competition. Reality is subjective, so providing proof in the form of testimonials can do a lot to sway someone to your way of thinking. Testimonials, references, and endorsements are worth their measure in gold, and you should employ them whenever possible.

When you give your employer a good value, they will be motivated to keep you even in the lean times. Nothing is more important to your career than making sure your employer is satisfied with your work, which will make them likely to use you over and over again. Working for companies where there is a lot of froth will present you with more money-making opportunities; understand that froth moves in cycles, however, and it is more important to have consistent work than to hold out for ideal market conditions.

One of the most important things you can do in your career is generate value for your employer far in excess of what you receive back. You can talk your way into a high-paying job, but you will not remain there unless you provide more than you take. Organizations thrive when all of their members produce goods and services efficiently. Your career depends on providing more than you take, and surrounding yourself with people who do the same.

The influence of relationships can inhibit business growth and lead to disaster. At the same time, however, relationships constitute your greatest assets in your career. All aspects of your job search and your career depend on the relationships you cultivate, so you must strive to form the best relationships possible. You must engender affinity and genuine connections with those around you to achieve success.

When people are aware of others’ expectations, they usually perform in accordance with them. Outside expectations can lead to either your success or your destruction; surrounding yourself with low expectations can, in turn, lead you to under-perform and further distance you from your career goals. When you surround yourself with people with high expectations, however, you will rise to levels you may not have thought previously possible.

Being unconscious of our surroundings causes us to miss out on many opportunities. We fail to notice many things immediately around us simply because we are not expecting them, and thus involuntarily tune out many potentially great opportunities. You must bring conscious awareness to the thousands of unconscious decisions you make in your business and personal lives. The more notice you take of the things around you, the greater your consciousness and potential for success.

In business, innovation comes from the freedom to operate; stagnation and failure result when a government attempts to legislate business. Limiting peoples’ ability to make a certain amount of money undermines business in an incredible way. Similarly, you need to associate with businesses and groups where freedom of movement will allow both you ant the company to expand. When you have more constraints placed on your movement, you face greater problems and eventually the loss of your job.

In this article Harrison discusses the reasons why the best executives are so highly paid. According to him the main reason for this is that exceptional executives are rare. A top executive has to make numerous decisions and calculations whilst taking every factor into account each day. There are very few people who have the capacity to organize people, increase productivity and profitability, all while facing criticism and driving a company forward. The survival and prosperity of a company depends on having people who can give good orders – and have them carried out by others. Those who can lead groups typically are the highest paid people inside corporations and groups. The highest paid executives are able to implement and get things done; the lowest paid typically are not able to do this.

You are rewarded in direct proportion to the value that you deliver, meaning that you have to deliver in order to reach your full potential. You will provide more value to others when you are focused on giving. People who under-deliver view their jobs as being primarily about them, while those who over-deliver see their jobs as being about others. Strive to develop a reputation for delivering rather than under-delivering.

In this article Harrison discusses the importance of concentrating on your work and not getting distracted. The true value of the best executives comes from their ability to concentrate and get things done. If you can concentrate for a long period of time on a single issue, you will improve the quality of the work that you do. The qualitative aspects of your work are incredibly important because they end up determining your outcome. Good companies and employers value people who are organized and think through issues when they are working on something. You need to concentrate. You need to give everything you are doing your full attention. You need to work hard and be focused.
