Firstly, they took an aptitude test. The test mainly consisted of four sections: C, OS, hardware, and analytical reasoning.

After that, there were two technical rounds and then an HR round. The main focus of the interviewer was on C, OS, and hardware. As the interview is for a test engineer, they expect a little bit of knowledge of software testing.

If you have any hardware certifications, then the process is much easier.

The puzzles were little but tricky. They do not expect the right answer from you, but the logic of how you should get the answer to the puzzle.
