I applied in-person. The process took 2 weeks. I interviewed at Trader Joe's (Concord, CA) in Mar 2016
Interview
Walked in with my resume on a Monday, first interview was scheduled immediately for that Thursday. As soon as the first interview was over I was scheduled for a second. Second interview went very quick, the mate just pretty much went over the answers I gave to the first interview and said they would contact me the following week. Didn't get the job for some reason.
It's two to three interviews, the final with the Captain (or highest manager) of the store. The interviews are largely to get to know your personality and how well you would do at customer service.
The interview process was absolutely wonderful! I didn't feel stressed or nervous and it felt like I was just chatting with a friend! Trader Joes is a great company and the interview was great.
Very chill, asked things a lot of job interviews don't, more personal down to earth questions. Made me feel very comfortable. Professional but also cool vibes from everyone who interviewed me. Went to one interview with mates and another with the captain.
