The interview process involved three rounds. The first round was a written test with three sections covering electronics, mechanical, and computer science fundamentals. The second and third rounds were both personal interviews, both technical in nature. The questions focused on electronics and communication basics, as well as data structures and algorithms programming questions based on these topics.

Technical Coding
The interview involved asking detailed questions about diodes and how they are tested. I was shown circuit diagrams and asked about current and voltage ratings. They also inquired about my practical knowledge of IC testing. The onsite interview had three people asking me separate questions for about an hour. Understanding the basics of electronics components is crucial for this interview.
Confirmed questions1 question
- How important is the real time constant for testing?
