I applied online. The process took 4 months. I interviewed at Electrical and Mechanical Service Department
Interview
First interview was a group discussion problem; There were 4 people in our group, we had 16 minutes to discuss on a social problem after a 1-minute self-introduction. Group discussion was in English the entire duration;
For second interview, first you have the written test. For the written test, you will be asked to draw 3 questions from 5 from the question bank and then write an essay based on one of the 3 questions. As for the interview, it was mainly technical questions based on your technical background on whichever field of engineering you applied to.
