My interview felt almost painless. It leaned heavily on a role-play format with basic interview questions, and the manager who spoke with me was genuinely friendly, which took the edge off right away. I remember thinking the whole thing was more about how I came across than any high-pressure test.

I didn’t get a decision immediately during the interview. Still, the timing was quick—an email arrived the very next day offering me the position. Overall it felt easy, even though it included some simulated scenario work.

The process started with an assessment that felt less like a formal test and more like a “how do you work” check. After that, I moved into two additional interviews. One was with the store manager, and the other was with a peer of the manager from a different store.

It wasn’t the kind of experience that felt overly intimidating. The interviews stayed grounded in practical, on-the-job perspectives, and the assessment gave me the sense they were trying to understand how I operated day to day before getting into deeper discussion.
