I had a very disappointing interview experience with UBS for a Data Engineer role. Two interviewers joined the call without any introductions. When I introduced myself, one of them responded with a sarcastic “interesting” and was consistently rude and dismissive throughout. I was interrupted repeatedly, which made it difficult to communicate effectively. Feeling uncomfortable with the tone and lack of professionalism, I chose to end the interview early. This experience reflected a concerning lack of respect for candidates. I would advise others to be cautious when considering opportunities here.
