2 rounds of online interviews (HackerRank etc.) with 2-3 questions each. 1 onsite full day with 4-5 different engineers each for about an hour each. Asked all kinds of programming questions, including algorithms, graphs, trees etc.

Two round virtual interviews were conducted. One was a LeetCode-style "stack" question, and the other was a dynamic programming question on the Fibonacci sequence. Overall, the experience was very good, but the two interviews were scheduled back-to
