Very quick and easy process, two rounds. Both focused unexpectedly only mainly on grilling my resume and verifying I actually knew what I was talking about in regards to engineering processes/etc. Just review engineering fundamentals and know your projects well for internship. Took less then a month total.

The interview process consisted of two phone calls (one interview and one call back interview), and the interviewer was a senior engineer on the team. Sometimes it is the lead engineer, but in my case he was busy.
