Experian interview questions

I get the interview from a referral. The manager of Experian lab connected with me and we made a photo interview. I am really disappointed about this interview even though the manager was very nice during all the processing. But he never connects with me anymore after the interview. I tried to email but no reply, until my friend asked the staff in the Experian I know I was not passing it. But I really answered most of the questions correctly and had a good time to take with the manager. I can accept they do not give me offer but I could not accept they lost the connect and never reply to my emails.
