I sent an online application on Tuesday and received an email less than 24 hours later to tell me I got an interview for the following Monday (so a total of 6 days passed between my application submission and my interview). I wore casual clothes - white tee, black jeans, and grey Vans. I arrived 15 minutes before my scheduled interview and notified the cashier. The interviewer came out with two other workers and we sat down at a table in the dining area. She asked me a few general questions (age, school, prior work experience). Then the two other workers asked me a few questions but it was very casual. After the questions (which took about six minutes) they took me in the back to show me around. Afterwards they brought the manager out and he informed me that I got the job. The whole interview took less than 15 minutes. Everything was relaxed and everyone was friendly, they even gave me a burrito bowl on the house.
