Rose,
Most interviews these days are competency based and are scored accordingly eg.....
1) How do you deal with multiple workloads / working for more than one boss
2) Give me a time when you had to deal with a difficult customer and how you dealt with the situation (hint: a customer can also be your boss)
3) Identify a problem and the steps you took to resolve it
4) Give me an example of a time you had to work as part of a team
Of course these are only some of the questions you might be asked. You might also be asked how you feel your skills and experience meet the criteria for this role. One other question I have been asked recently is, give 3 words that others might use to describe you.
Interviews are 2-way and whilst the panel want to get to know you, it's an opportunity for you to find out as much as you can about the role and the company.
I wish you the best of luck. Check out this website for some extra tips. I have used it a lot in the past -
