I recently applied for a part-time position at a clothing retail store. I had my interview on Friday, but it felt very rushed and I didn't think it went well. The interviewer mentioned I would hear back by Tuesday, but I received an email on Saturday saying I was unsuccessful. I brushed it off, thinking it was fine. However, on Tuesday, I got a call from the interviewer saying the other candidate didn't accept the position, so I was still in the running. He also mentioned he had two more interviews scheduled for the next day and would let me know afterward. It left me confused about why he called if he was still interviewing other candidates. Is this a common practice for employers to keep candidates hanging like this?
