I applied in-person. I interviewed at Trader Joe's (Manchester, CT) in Aug 2018
Interview
They ask you about their brand, what your favorite product is, and what motivates you. You can look great on paper, but you need an empathetic and passionate personality as well.
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.
