Contacted by recruiter via email. The recruiter then set up a virtual zoom interview with a senior engineer. Interview lasted about 30 minutes. Asked technical questions and questions about experience.

First screening included a 45 minute interview that went over the technical aspects of work experience and then additional technical questions at the end. Technical questions were not overly difficult and were mainly over signal processing. The interviewer was extremely nice and was even on vacation. It has only been a few days so I am still waiting on a follow-up.
