Standard 3-step interview process:

1. Initial recruiter phone call to gauge candidate fit.
2. Technical screening with two engineers over online video.
3. On-site a couple weeks later with 5 to 6 engineers/managers.

Pretty simple technical questions.

Non/inverting amp, voltage divider, DC blocking coupling caps, some logic gates, truth tables, etc. Mostly just verifying that you know about things, not so much depth of knowledge.

Questions are mostly behavioral about how you feel with challenges on projects: what was your most challenging project, situation where you had to deal with someone not performing, how you did what you did and why, etc.
