Asked to 'help out' at one of their presentation center for 1 day only because their team has other commitments and need reception help. I was interviewing for a Marketing Manager role. Since I am interested I the job I did the 6 hour shift, only for them to get me into a second interview which the Director 'forgot' about the interview and another random manager chatted with me for 15 minutes not knowing what's going on. Long story short got scammed to work for free.
