The interview was with a manager and another team leader joined after. Both were very nice and made it a relaxed interview. I got an offer a few days after.

Informal and casual, they made me feel very comfortable. it was a group interview of 2 managers and myself. they asked me the usual questions but then threw in some informal questions about myself. overall, it was very relaxed interview. i did not feel nervous, but my interviewees wanted to know more about myself outside of work, such as volunteer work, enrichment classes, and etc.
