I started as a tier 1 employee 4 months ago and was guided through the process to apply by my front half and back half area managers. There was a math problem like you would have done in high school. Basically you own a deli it takes X amount of time to make a sandwich how many sandwiches can you make in a shift and what can you do to increase the amount of sandwiches made? Don't read too far into it or you might confuse your self. Then you choose your preferred days or night and front half or back half shift. Afterwards you go into a room and explain your answers to the math problem. Roll play coaching an associate and then there's some personality questions.

30-40 minutes depending on the interviewer. There might an aptitude test as well. Three rounds with different departments that might involve learning, HR and operations, with each interview going for about 10-15 minutes.
