O2 Retail Advisor interview questions

Interview was a 2 step process. First was a telephone interview asking the basic question like right to work and some competency based questions. I passed that and was onto the face to face interview. The interview was a normal interview asking strength based questions. I wasn't really fond with this interview as the interview seemed like he didn't want to be there. I got declined for this interview which I wasn't expecting as I have the experience and thought I did well in my interview. The thing that really annoyed me with the rejection email was that it was sent at half 3 in the morning which is really unprofessional and not a nice thing to see when you wake up.
