I applied through a referral program and received a call from HR to schedule the first telephonic round. They asked questions related to debugging code and identifying cases where a particular code would fail. I had two more telephonic managerial discussions, after which I was invited onsite for a full day of interviews.

There, I had three technical rounds:

• The first was a written round, where they provided a problem statement and I needed to come up with a solution within two hours.
• The next two rounds were technical, where I was asked to code, solve puzzles, and discuss a few design-related questions.

HR and all the interviewers were very welcoming and made me feel comfortable throughout the day.

They released the offer a week later.

Questions were mostly based on DS, algo, debugging, and design-related topics.
