It was an ok experience, mostly circuit-related questions and some conceptual stuff. Make sure to review circuit analysis and other electrical engineering concepts that relate. Good luck. INterview lasted about an hour and It was with the senior engineer on the team in a location in California

Smooth process, started by asking technical questions in the first interview, 2nd interview with manager and more on conceptual problem solving questions on their current project. 3rd interview is typically a long panel interview. Gave a generic feedback after not proceeding
