Tips for new job seekers: Interview preparation part 1
Relevance and practical values in the job are the real issues with all interview questions, on any level. It is quite possible to give an answer which has almost nothing in common with the requirements of the job. That's not where you want to be.
Important note: If you're not sure what a question means, ask for clarification. Don't try and bluff your way through, because it won't work.
The problem for interviewees is that the exact meaning of the questions isn't always obvious. You have to respond to what might seem to be a cryptic question with a very clear answer. If the question is something like 'What do you consider success in this field?', use straightforward analogies and examples.
Simpler is always better. You can extrapolate on a simple answer, but you have to explain a complex one. Interviewers aren't interpreters. The clearer you are, the better you'll do.
