The interview itself isn't that difficult but since there are way too many steps in a short amount of time, it's easy to mess up ... the process is as follows: This is for full time entry level software engineering position: 1) Phone interview with a recruiter 2) Take home coding assessment (Takes about 3-6 Hours) 3) Review of the coding assessment & speaking to multiple higher ups (could be between 1 to 4-5 interviews) 4) On site which takes a whole work day usually (Panel and speaking to 4-6 different engineers) Overall the people are friendly but the are so many steps... in my case because the process was taking a looong time and I landed another great job I had to withdraw my application mid interview process.

coding assessment including DSP related topics, take home with test cases. full test had unknown test cases that were extensions of given tests. Also included phone technical interview, coding fundamentals and RF topics
