A recruiter contacted me and said that they were interested in my profile and asked me to send them a resume. Initially I was invited for a remote technical interview which went very well (in fact I had no wrong answers!) They later said that they wanted to continue the interview process. They wanted me to do a project for them within 24 hrs. Since I was busy I asked if I could do that in weekend and we agreed that they send it on Friday and I send the project back on Saturday. I cancelled all the plans for the weekend but did not receive anything on Friday. On Saturday evening I finally contacted them that I was waiting for them all Friday and they suddenly remembered!!! The project was send to me on Saturday night and I ruined my weekend for an offer I knew they wouldn't give me. I have to say it was such an unprofessional behaviour and waste of time.
