In his book, The 48 Laws of Power, Robert Greene (e-book edition, p. 237), provides a great description of the game of chess:

Chess contains the concentrated essence of life: First, because to win you have to be supremely patient and farseeing; and second, because the game is built on patterns, whole sequences of moves that have been played before and will be played again, with slight alterations, in any one match. Your opponent analyzes the patterns you are playing and uses them to try to foresee your moves. Allowing him nothing predictable to base his strategy on gives you a big advantage. In chess as in life, when people cannot figure out what you are doing, they are kept in a state of terror—waiting, uncertain, confused.

Of course, in a job interview, you are not facing an opponent but rather individuals who you want to become your confederates. Yet, there are similarities to a chess match:

The most difficult part of a job search is patience. You have to wait for a response to your application. You have to wait for a response to your initial (phone) interview. You have to wait for a response to your in-person interview(s). And you have to wait for the job offer. Perhaps serving in the military is a great preparation for conducting a job search as, at least based on my experience, most of the time you just sit around and wait!!

Being able to foresee the steps in the process is crucial. If you expect that there will only be one interview, and it turns out you will have to have multiple interviews and a test, you will become disheartened. The solution is quite easy: Ask! There is no reason in the world for the process to be kept a secret. If you know what to expect, you can prepare, most importantly, psychologically. The key to getting a job offer is confidence. Confidence is an emotion. If you are projecting depression, because you don't like the hoops through which the employer is making you jump, you might be confident you can do the job, but you won't be confident that you want the job. Employers can read emotions so, as your emotions are the most important thing you bring to an interview, you have to protect your king - confidence!

Finally, note what was said about patterns in chess. The analogy in interviewing is that different interviewers will ask you the same question(s). Then they will compare your answers. They don't have to be word-for-word identical, but if they are different, you can forget about getting an offer. In that case, you have lost your king and are checkmated.
