The interview process was pretty quick, but there was one weird thing (red flag here). After completing a week long training (which I wasn't paid for by the way) and working full-time without an offer, I didn't receive any communication from my manager during that week. Instead, I received an email from HR saying, 'Sorry, we've chosen someone else.' There was no feedback or explanation provided. I worked a full week for them, only to receive a simple 'sorry' message in the end. A bit frustrating to be honest.
