I applied several positions from the career website and got an email notice for a phone interview a couple weeks later. The interviewer was very professional and nice. He asked me to explain my experience from the resume and asks specific questions about my experience and general C questions.

There was an initial virtual meetup to go over the job role and walkthrough CV, followed by a two hour long technical interview. Many aspects of DSP and software engineering were covered including, multi threading, rate matching and data structures.
