I applied recently through job fair.Have my initial interview then exam.The exam took 20 minutes for 3 sets.After that they will tell you if you passed the exam.I've passed the exam then waited for another interview.The interview is more on personal experienced,actually it is rasy for me.Then the interviewer told me to wait for a call for one to two weeks.Before I go,I asked him about the call and he told me its job offer.I felt positive about it but it seems that they will not call me anymore.I'm still waiting up to now.
