Invitation message from piazza, and a few weeks later, took a test by hackerrank. It was overall knowledge of basic electrical engineering and some portion of coding problems. After that, I got invitation for on-site interview and it was 4 interviews for 45 minutes each.

Applied online. They got back to me fairly quickly. to set up initial phone screen. Then, shortly after I moved on to the on-site. They claimed they'd pay for the gas I used to get there but they didn't. On-site went smoothly, everyone was nice. 4 45-minute back-to-back interviews
