6. What have you learnt from mistakes on the Production support field?

21. What would your previous colleagues say about you?
This is not the arena for full disclosure. You want to stay positive and add a few specific statements or paraphrase. Something like "Joe Blogs always mentioned how reliable and hard working I was" is enough.
This is probably the most asked question in a interview. It breaks the ice and gets you to talk about something you should be fairly comfortable with. Have something prepared that does not sound rehearsed. It is not about you telling your life story and quite frankly, the interviewer just is not interested.
23. Why are you looking for another job?
