Absolutely agree with above, and btw, the business school of Warwick is top one in UK. However, the life there is bloody boring... Anyway, goog luck to you
No technical questions at all. It mainly focuses on your soft skills. School just wants to see whether you will participate to class discussion, how would you perform in the future job interveiws. Qustions are pretty common, such as self-introduction, why mif, your career goal, your career path, why do you switch your jobs, teamwork etc. Good luck.
