River Island Part-time Sales Advisor interview questions

The interview was really quick and relaxed the manager was very friendly, I applied for a part time Monday to Friday 11-4 , 12-5 I these were the hours advertised on the website, however when I got to the interview it was totally different hours which I couldn't do, I'm very disappointed that river island did this, I personally believe I didn't get the job because I mentioned I had children and wasn't able to work late nights or weekends I know it's retail, but I feel it's discrimination to be honest!

all was terrible in my point of view, interview started 5 mins late, but thats ok, after they start check documents, since I am not from EU and UK the only proof of work is residence card, but manager insets she need passport or she will send me away, after I asked my friend to bring it, they were not interested in anything I tell, just waste of time!!! All the manage did was listening herself and making show! It was terrible 12 people!! 12!!! how can u pay attention to any? At the end of interview when my friend brought me passport they told they do not need it! they made me stressed and the attitude to me was like I am nothing!!! Just in case.. I have more than 10 years experience and education and the rest were 11 were students for whom it was first interview in there lives. The worst interview ever!!!
