Round 2 was a 45-minute face-to-face interview focusing on my background and a Recommender system project, along with questions about BST, complexity, finding the kth element from the end of a linked list, and the next greater element in an array. Round 3, another 45-minute face-to-face, involved background discussion and a question about finding the most frequent elements in an array with an O(N) expectation. Round 4, also 45 minutes face-to-face, included background talk and a question about finding the next greater permutation of digits.

Round 6 was a 30-minute face-to-face with the India head, involving detailed background discussion, project talks, some behavioral questions, and company information.
