i would say on 2nd interview you are probably potential candidate <shortlisted> to hire by them ... well on question, it's quite subjective imo depending what job position you apply for .... eg if on engineer post ... should prepare yourself .... on technical aspect i.e how to solve prob by using various tools, tech drwg, what software, any project taken etc .... again i'm not sure they will ask you this??? IF asking WHY you are suitable for this position then at least you must able to demonstrate / link your previous job experience or accomplishment to your future employer, just my 2 cents ..

cheers.

i assume you are graduate with eng'g in mech or elect or industrial....etc background?? just my guess aah, probably they will touch on what design you propose or project etc you had taken during your studies (fresh) or your existing job <what you do and accomplishment>, autocad or any eng'g software you familiar with, any equipment / tools used..... bottom line to relax and don't give so much pressure to yourself if not then you will be gelabah/ kelam kabut during interview .... so no worry friend, there are plenty of opportunities out there and wish you all the best ... good luck in your coming interview

**** you can check with your friends if you have <anyone work in r&d dept>

cheers.
