So I had a interview yesterday. And they said they would be able let the person know at the end of the day. In between then I've been offered another job which I've accepted earlier. I've just had a missed (they are now in a meeting) asking to ring back. Another candidate also had a call saying the were unsuccessful. I'm now getting nervous about ringing in case they offer me the position although it now seems unlikely. Would it be acceptable to email them that I've missed their call and have assumed I've been unsuccessful? I'm happy with he job I have accepted anyway.
