The interviewer spent almost 5~10 minutes to explain the structure of the team and the available openings. After introducing myself, I was asked whether I can make the onsite interview on the following two weeks and how long I can work for them. Then, the interviewer went straight to the technical questions including some brain teasers. The total interview was an hour.
Interview questions [1]
Question 1
I took a technical aptitude test; however, the interview questions were irrelevant to the test. The interviewer gave me a case scenario on the optimization problem and the simulation problem. Overall, the questions were all technical. The interviewer also asked me how long I can work for them.
