I applied in-person. The process took 4 weeks. I interviewed at Trader Joe's
Interview
It was very casual and in the back of the store. Two managers and another crew member interviewed me. They asked me basic questions regarding school, extracurriculars, and availability. They also asked about my interpersonal skills.
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.
