I can't remember if I came before or after they started walk-in interviews but I went in, waited awhile, then met with someone for the interview. His demeanor was rather cold but it was quick. He pretty much just asked questions to see if I'd show up and if I'd be willing to work overtime.

Interview was easy and straightforward. The interviewer only asked around 3-4 questions about your background, strengths and weaknesses, as well as work preference. Nothing really challenging about it at all. I had received a job offer immediately after.
