I applied in-person. The process took 2 weeks. I interviewed at IBM (Singapore) in Apr 2012
Interview
2 rounds. First with my manager and then with the BU director. The manager knew me before so it was quite a easy process. HR will call you for salary discussion. Stay firm on your requirement. Remember to ask them in details of the benefit as IBM has quite good benefit.
I applied through an employee referral. The process took 4 weeks. I interviewed at IBM (Hong Kong) in Mar 2011
Interview
2 interviews in total, one with line manager and last interview with second line manager. No abnormal questions asked, all questions are typical interview questions.
