I applied in-person. I interviewed at Trader Joe's (Washington, DC) in Nov 2016
Interview
Conversational. Cheerful, laid back easy. Two part review. You review with manager on the spot. They will ask you why Trader Joe’s and describe what you are signing up for. The they will cal you and you will interview with boss
Applied online and had one in person interview with the captain. It lasted maybe 10 minutes. Got a call a week or so later that I got the job. Very fast process.
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.
