Very easy, hire on the spot interview process. I would recommend dressing professionally although not required. The process was easy and they are flexible with schedules. I would recommend if you want extra money.
It was a brief interview, the manager asked me a few personal questions and then asked me to join the team as a temporary member. Furthermore, he said that If I met their expectations, I would be upgraded to a full-time employee.
I applied in-person. The process took 3 days. I interviewed at Shaw's (Boston, MA) in Mar 2019
Interview
It was fairly easy and it required mostly just honesty. The job review was more of a moral and personality check. Overall I enjoyed the experience as it was my first.
