EF (Education First) Internship interview questions

I received a phone interview at the beginning, and then after 2 weeks I had been selected to the second round for the on-site interview for the whole day. I was interviewed with 4 people in the team. 3 of them are okay, nothing special, but one of them gave me some pretty bad impressions: he was apparently some former employee of a famous gaming company and he hates gamer, and he showed his such attitude towards me in the interview with some pretty cocky tone. The overall difficulty is not hard, but I was not preparing well to get through because I was extremely busy with my other stuff. On the other hand, what makes the worst thing is that the promised reimbursement on the round-trip train ticket never actually arrived after replying the email about the reimbursement. There was no further reply afterwards about rejections or progress, either.
