Interview Mistakes I took a poll of several hundred human resource and hiring managers and asked their opinion on what the ten worst interview mistakes were. The following were the answers. I was surprised by a few of them, and some of the ones I would have included didnt make it to this list, but its a good start. Many of these transgressions are no brainers, and yet, candidates continue to get it wrong. Quite often it costs them the job offer, which ends up going to a person with less qualifications. These are simple things, so take a look and make sure nothing on this list disqualifies you on your next interview. 10. Dont forget to turn off your phone. I know this should go without saying, but I cant tell you the number of timesstillthat I have clients tell me they were in the middle of an interview and the candidates phone rang. This is an easy one, people. Dont mess it up. 9. Dont Use Offensive Language. 8. Dont Let Body Language Rule You Out 7. Dont Come To the Interview Without Questions Common sense will tell you to be prepared for everything. But its suicide to come without having done some research on the company and coming up with a list of questions to ask. When an interviewer asks you, Do you have any questions? You better have a list handy. They arent usually interested in the actual content of the questions, but they do want to see how deep you dug in your preparation. Almost every person I polled had this on their list at one rank or another. 6. Dont Say Anything Negative 5. Dont ask about compensation. When I say this, I dont mean just salary. If this is the first interview, keep the focus on the position and your fit for it. Dont ask about salary, bonuses, stock options, vacation, or anything else related to the compensation package. There will be time enough for that later. When you ask about compensation at this stage, the company thinks thats all Most hiring managers agree that being late is one of the most grievous sins. They have scheduled an entire team around your interview. Most of the people youll be interviewing with are busy. They cant afford to have their schedule thrown out of whack because youre late. Dont make your plans around getting there on time. Make plans to get there at least fifteen minutes ahead of time in case something happens. If all goes well youll be early, and theres nothing wrong with that.
