I just had a interview which went well, I don't think I got the job but the interviewer was asking behavioural questions from a booklet it seemed.
Also be prepared to go into great detail because they reference back to what you say in later questions.
A lot of the stuff everyone said so far is pretty much true, first question I was asked was about my 5 year plan. Then it got into questions that didn't really relate to the job at all which was frustrating, but I did prepare for them so it wasn't catching me off guard.
Tell me about a time you saw a project to the end? Tell me about a time you didn't see eye to eye with a teammate? How did you handle it?
I think the questions that gets people is tell me two things that you think you can improve on? No one wants to lists negatives about themselves, so I was told to list things you do really well, but add in maybe if I don't put so much time into such and such I could be quicker.
Another one that comes up is if you never actually experienced something they are asking? Tell me about a time you had to fire someone? You can say well I have never been in that position, but in the if I was put in a situation like that this is how I would handle it.
Key is too look them in the eye, smile, and if they don't hire you after grilling you for almost 90 minutes pee in their water
