There are 2 interviews in total. The first 1 is the typical interview with typical questions. Before staring the 1st interview, the HR will ask to solve a simple engineering calculation problem. It took around 2 weeks of processing time to shortlist to 2nd interview. They required to present 2 questions in 2nd interview to test on the thinking skill.

It was an interesting interview. The interviewer asked a couple of common interview questions (Introduce yourself, why do you want to work for this position etc). Additionally, he also asked a few questions to test on engineering knowledge. (formula, creative thinking etc)
