Ok so have another interview tomorrow and wondered if you guys would like to help me? Ask me some questions, get me on the ball. Workwise or personal questions
Where do you see yourself in five years' time? (I always hate this one at interviews - if you say still doing this job they may see that as lack of ambition but if you say progressing up the career ladder thay could think you're just using the job as a stepping stone!)
A good answer to the biggest mistake thing could be something like "I didn't have the confidence to apply for a supervisor position but looking back I think I could have done the job very well"
