one case question, pretty easy, some behavioural questions, asking about how you deal with stress and your experience about working with other people there are also some basic questions. For example, she asked me when will I graduate and what is my plan after university

Drawn out and people seemed unhappy. Didn’t get offer until months after I had final interview. I declined because I had accepted an opportunity some where else. I did not have a great experience with the recruitment team at Mercer.
