I applied in-person. The process took 1 day. I interviewed at ITX Solutions (Singapore) in July 2012
Interview
The company is often in need of part timers during the school period but this varies between schools.
Hiring process is simple - you just have to meet up with the boss who will explain what you have to do. He might ask you some questions about yourself and why you wanted to do this but those are fairly simple to answer and harmless. The interview is informal.

Question 1
Nothing too tough to answer. You are just a part-timer.
