You likely have heard that interviewing is like dating. Or interviewing is a complex dance with lots of steps. The translation: Interviewing is a unique conversation where there seem to be many rules and traps that could lead to failure. You can interview almost perfectly and still not get the job. Like professional sports, you can have a good season and still not win the biggest game. (As a Cubs and Bears fan, I am well familiar with getting close and still losing.)
