I applied through university. The process took 2 months. I interviewed at SMRT (Singapore) in Apr 2018
Interview
The first round was an online test. The second round was assessment center with a written test and case study group discussion. The final interview was with the senior management from different departments. Overall it was a simple interview with basic competency based questions.
