UBS interview questions

The recruiter conducted a short phone interview then scheduled for in person interview in the investment center in Lincoln Habor Center NJ. The interview consisted of 3, 30 minutes sessions with a peer, the manager and the branch manager by phone. The interviewers introduced themselves and conducted a conversation related to candidate work experience, job nature of the position, the interviewers asked the candidates if they have any questions. There are questions related to how to handle difficult clients and colleagues from both the peer and the managers multiple times. The branch manager did not show up at the end for the phone call. The recruiters did not follow up or provided response until a week later.

first round, phone interview, I applied the Singapore office, and they give me this 30 min interview over calling me in the morning. One of my classmate got through the 1st round interview and the chance to go to New York for 2nd round, still wait for the result. I thought the reason I didn't prepare well is not successfully present the advantage I have and showing my skills
