I applied online, and HR reached out.

The first interview was with HR to see where I stand.

Then, an engineer from the department interviewed me, asking more technical questions related to my resume.

This was followed by a more technical interview where I was asked to write down circuit questions and solve/explain them.

I was then given a 24-hour assignment, which included design/business questions and four pretty difficult circuit questions.

It was followed by two more phone interviews by a different engineer and an engineering manager.

I was given a 24-hour assignment for op-amps. The questions are confidential.
