1. Corporate RM (there are 4 frontline depts in GCB, i only rmb one is local conglomerate and others are mainland companies, e.g. TMT)

2. Yes GT offer is guaranteed (like a safety net) if u get the final interview

If the format doesnt change, the final interview should include a presentation. My advice is to choose a more difficult question, and some backup slides might help (as the presentation time is too short for u to explain all the details).
