Went to a career fair at my college and gave them my resume. They scheduled an in-person interview.
The interview was mostly behavioral - asked questions about working in groups, how I have dealt with challenges among group members, how well I think my verbal and writing communications skills are, if I have used oscilloscopes, multimeters, etc. The only real technical questions were what does DC coupling mean to me, what do I think an embedded system is, etc.
Then, within two to three weeks, I received a phone call from an HR recruiter saying I got the job and they sent me an email with the details. Told me to fill out an application and background check stuff (nothing too detailed). I got the official offer and accepted it.
Overall, a very simple and easy process.
