4 rounds, out of which 2 were DSA rounds and the next 2 were system design rounds. DSA questions were typically medium to hard, from LeetCode level, mostly relevant to DP and graph.

First round of QA: 3 hours in length. This round included: * Multiple-choice questions. * Questions regarding conversations, for example, a conversation between two employees about a project. * Some code correction questions. It was an email-type

Very good and unique, especially the parts that were not timed. The questions were practical, based on actual scenarios that a QA encounters in their day-to-day work. There was no need for preparation for the sections that were not timed.
