I had two phone interviews. The first phone interview had two questions to solve. The second phone interview had one question, but extensions to the problem were added later.

I did well and was invited onsite. The onsite interview was a typical six-hour session with one-hour rounds.

There were:

• Two coding rounds
• One design round
• One round with the hiring manager
• One technical communication round
• One lunch

In each coding round, I had to solve at least two coding questions. It was important to be fast and ensure the code was correct to the most granular level. All questions were LeetCode medium level. I was encouraged to solve as many as possible.

I experienced a hiccup in one coding round and ran out of time to complete the code for the second question. This was a significant reason for not receiving an offer.
