From Hackathon to Hire: My UBS On-Campus Interview Journey

Round 1 – Technical Interview

The first round was completely technical and focused mainly on my resume, projects, and internships. The interviewer asked detailed questions about my projects — what they do, what makes them unique, and the technologies I used. I was also asked a simple DSA question based on arrays. Since the problem was easy, I shared two to three possible approaches, coded the solution quickly, and also explained the time complexities for each approach. The interviewer seemed satisfied with the structured way I explained my thought process.

Round 2 – Technical + HR

The second round was a mix of technical and HR questions. Due to a brief network issue, I joined the meeting a minute late, which initially made me nervous. However, the interviewer was extremely polite and helped me feel comfortable. The discussion started with introductions, followed by questions from core computer fundamentals like the difference between private, public, and protected. Once again, I was given a simple DSA problem to solve, where I had to write the code in the chat box itself (no need to run it). Again here I gave 2 approaches and coded them up.

The interviewer then mentioned that UBS doesn’t just look for talent, but for sharpness, and asked me a puzzle to test my logical thinking.

• “A father and his son met with an accident, and both were taken to a hospital. The boy was badly injured, and as he was taken into the operation theatre, the doctor said — ‘I can’t operate on this boy, he’s my son.’ How is that possible?”

Toward the end, there were a few situational HR questions, and I got a chance to ask her one question as well — which turned into a 10-minute discussion. I would definitely recommend ; it helps create a good impression and makes the conversation more engaging.
