Probably most common mistake I see in people consistently make is to not engage with the interviewer. People naturally like people they can have a good conversation with. If you are answering questions too succinctly it can be a problem. I was on an interview the other day where I was basically trying to guide the candidate down a certain path. This candidate was answering my questions, but they were not doing much more than that. I was hoping to have a dialog with the person to delve deeper into their background and skill set, but it was almost impossible without me doing all the talking. I even went so far as to asking a purposefully vague question in hopes this person would ask me to clarify. It is a technique I like to use to see how people deal with ambiguity and how good they are at asking meaningful questions. No such luck. The person just answered the question.
So my advice is simple. It just involves
- Asking lots of questions - If you are asked a question, ask a question right back. There are no perfect interview questions. Almost everything in life can be clarified. I like it when people are confused about my question. It shows they are paying attention and that they are being thoughtful about their response.
- Talk and be verbose - Don't go overboard with this one but remember that this is a conversation. You should probably be talking as much as the interviewer. There are times I have gotten the interviewer talking more than myself by asking the right question. More often than not, I do well in those interviews.
So don't be shy. You would be surprised how often interviewers wouldn't mind a helping hand for themselves when trying to get through an interview.
