Nobody actually likes to go on a job interview (you could be doing something less stressful with your time—like drinking in a bar or climbing Mount Everest).

It’s nerve-wracking for the interviewee. It’s a time waster for the interviewer. And it’s just an awkward experience all around.

After all, this one little interview could determine your future. What should you wear? Should you dress up or dress down? Is a suit too formal? Do you make eye contact? Or should you not make too much eye contact?

Your mind can go crazy agonizing over every little question. But the truth is, there’s just no one way to act in a job interview, since every company is different. Remember: hiring managers are people, too, each one having their own unique set of preferences.
