I was offered at grad position at a company I interned for 2 summers ago, but due to the fact I decided to take a year and do some research a university in the US, for this reason I had to turn down the offer but I told all this to the company and I said I would love to work when I come back.
I now have a interview for that company and they said I just have to come in for 1 interview due to the fact it has been a year.
My question is what kind of questions should I expect, also what type of question should I ask the interviewers at the end. Normally I ask questions like what your day like, and best thing about this company.
P.S. Also my interviewers are people I already met and have socialised with over drinks during the internship.
