Totally unsure what to do. I have 3 job offers, declined one as they email giving me tile to think. I then had two further interviews typically the same week. The 3rd job didn't get back to me when they said so thought I didn't get it, so I accepted the second job which I was happy with at the time but now the 3rd offer has come through. My friend had applied for the 3rd job and she has been told she didn't get it which is strange as I thought they would have contacted me first to see if I wanted it. I feel absolutely torn and stressed about the whole situation. Is it totally unprofessional to withdraw a job I've accepted or to refuse a job when they asked at the interview if I wanted it. Obviously I did at the time but they didn't get back to me when they said.
