Paytm Software Engineer interview: DSA, wallet design, and Java

After speaking with a recruiter, I had a medium-difficulty DSA technical screen about a week later. It was a straightforward checkpoint where I needed to communicate my reasoning before, during, and after coding.

The next round was harder. I received a medium-to-hard tree problem and a system-design prompt about Paytm Wallet, so I had to move from an algorithm into design trade-offs. The last technical round combined core Java, questions based on my resume, and Kafka. That felt most tied to the role because it connected language basics to my background.

Location: Noida. Overall feedback: positive. Offer status: no offer.
