Investment Banking Analyst (graduate program)

After two stages (cv screening and online tests ) several weeks passed; then I was contacted via phone and invited for the interview to UBS office.
They were interviewing people for like the whole week, around 10 people every day (5 in the morning. 5 in the afternoon). First all 5 of us were sitting in one small conference room and completed two or three tests (standard SHL tests - verbal, numeric and maybe English, I do not remember). Then we all were moved each to separate rooms where each of us had interviews with HR specialists, Some questions were behavioral, some were IB-related. A lot of questions were about UBS are unfortunately I was not comfortable speaking about it. I guess that was the main reason I did not pass this stage.
I know that for those who passed two other recruitment stages were assumed: interview with IBD associates / VPs and then assessment center (no idea what is there).
