Applied online and received a phone call confirming availability of shift times and pay. I was scheduled for a test/interview after that. They have you do a math and English test first. If you pass then you move to the interview stage. I waited in the lobby until HR brought me to their office. It was mostly questions about my previous positions and experience. After the interview with HR I was scheduled for another interview with a shift manager and shift lead. I remember the questions being more difficult than with HR. The manager and lead took turns asking questions from a list. I think mostly behavioral questions. I remember receiving an offer about a week or so later.

2 part process. Onsite testing, interview, site tour. If you do well here then you meet with your future supervisor. Testing is basic math and comprehensive. HR interview only took 15-20 minutes total. Very friendly people.
