The interview process was enjoyable. The interviewers were patient and explained problems very well. The questions were basically undergraduate level. They expect to know how you approach the problem rather than expecting a straight answer.

The interview lasted for about half an hour. The interviewer called on time. As it was for a hardware position, I was mainly asked questions on digital circuit design.

Difficult 4 rounds involving hiring manager, then recruiter, then team lead, then a day of 7 interviews across different team members. C++ and Python questions. Also had questions about sensor design and signal processing.
