When I first applied, I received the OA. It consisted of two medium LeetCode questions and eight multiple-choice questions. The time limit was 90 minutes, which was manageable. The topics primarily covered strings and array manipulation.

I was then contacted to proceed to the final round, which lasted three hours. It included one behavioral interview, one OOP design interview, and two technical problems.

In the technical portion, I was asked two easy LeetCode problems, and I was able to optimize one of them. For the design problem, the interviewer assured me I was on the right track and was very encouraging.

Although I did not finish the design problem within the allotted time, the interviewer reassured me that I performed well by asking insightful questions and remaining engaged.

You are given a list of numbers and a target number n. List all pairs of numbers in the set that add up to the target number.
