EF (Education First) Intership 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.

First they did a zoom call to interview us. They were really nice, they presented us the company. They interviewed several people at the same time. They asked about us and the things they liked about the things they saw in our resume and asked about it. Then they did a personal interview with just a few selected of us.
