recruiter screening -> hiring manager screening -> final round virtual onsite. brief question on my experience for every round, majority of the role was systems-based and technical screening. Alot of "how would you test X product or Y sensor, or Z sensor with obscure shapes, obscure conditions.

The hiring manager asked questions only about op-amps, not about sensors, while in the job description, only requirements about sensors and motors were described. It might he was interviewing just for statistics.

Interview team was friendly, and interview questions weren't hard in retrospect, but I still messed up due to fatigue and nervousness. Many interviews in one day can get tiring, so use allocated breaks wisely.
