Three Step interview process, I first interviewed with HR then with department manager. The last interview I had I met with four engineers that work in the department who asked me questions and told me about the position.

Overall - very slow. I applied online, and was contacted by a recruiter after about 2 months. Screening went well, just basic information about the role and if my advertised skills would fit. Scheduled interview with the head of audio about a week after - also basic information about the role but he was looking for some technical understanding of the role. We ran out of time, so we scheduled a 2nd screening interview with another engineer to close out any questions. Did well enough to go into panel reviews. There was a total of 4 engineers to meet separately for 1 hour each. Each one was responsible for a certain aspect of the product (DSP expert, mechanical expert, spatial audio expert, speaker design expert). Each one focused on asking about their expertise based on what I wrote in my resume.
