Applied online, was asked to come to an interview/3h trial shift. I came, no interview/questions asked, was just put right on the floor during a hectic rush hour. No questions about my background, no getting to know me or giving me chance to ask about the company, no asking at all about my previous experience. It was a pretty easy and straightforward shift despite the morning rush, thought I was doing ok but got home to rejection message. Feels rather exploitive and a waste of time, was is it really trial shift or they're looking for free labour?
