Got an email from one of the Principal Engineers to set-up an initial phone interview. The interview was about half an hour mixed with STAR behavioral and some technical questions related to MCU. After a week, got another email from HR for the entire day interview details with different engineers and managers of different teams back to back. It was a video interview due to COVID. All the interviewers were nice except the two in one of the rounds. They both were chief engineers and the interview was after lunch. I can see on their face that they were not interested in taking interviews. They literally yawned 5-6 times during 50 mins of the interview. Heard back from them within a week with feedback. Answered all most all the questions in detail. Interviewers were also impressed. But they told that my experience was not a good match even though it was exactly the same as they needed. Very disappointed after spending an entire day and that was also with perfect answers.

Multi-staged interview with multiple engineering groups. No real technical questions. Just spoke to experiences and how I would fit in their work culture. Personality questions seemed to be weighed more heavily.
