Don't be complacent
There’s complacency in HR when it comes to interviewing. The reality is, it’s very different when you’re on the other side of the interviewer's desk.
Knock out ten minutes at the beginning at the end for niceties and questions, and you’re down to 40 minutes. Your interviewer’s going to have 12-15 questions, so you’re down to 3 minutes an answer. If you can’t get your point across in that time, you’ve got a problem.
