UBS Graduate Trainee interview questions

There were multiple rounds with the HR team and various other teams of interest. Questions were focused more on fit and understanding prior experience. Overall, it felt comfortable and was akin to a casual chat with the interviewers being very open to answering questions regarding their functions and roles.

Cleared all the interviews involved with the final one being a meeting with the HR department. I was made an offer which i accepted and was told to wait two weeks for the contract to be emailed over. One month later and I was informed that I had to go through another interview again with another department. Once again, i cleared and was accepted and the very next week, I was told once again that I had to interview with another team AGAIN. Absolutely terrible experience with the HR hiring team. Little to no communication from them regarding any issues. Perhaps the most disappointing experience from an established company that I have gone through.
