Online cognitive assessments, hackerrank coding challenge, round 1 and 2 interviews(didn't get past second round). Round 1 and 2 were mostly behavioral with different managers, and a small case study question in second round. Recruiters are somewhat vague about interview content after hackerrank challenge

It was a good experience overall. The assessment was conducted online through HackerRank and was well structured, focusing on problem-solving, logical thinking, and fundamental technical concepts in a clear and manageable way.

Applied and next day received a hacker rank.
SQL easy,
BUT LEETCODE MEDIUM
Required depth first search of an acyclic directed graph, and minimize the required changes so that a condition could be met.
SQL took me like 8 min but the LEETCODE one I couldn't get right. Code complied and all but didn't pass the test cases and timed out for some.
Hadn't seen or practiced a tree traversal question in years much less one that combined trees with minimization problems

Similar to LEETCODE 1135 but harder.
Had two dozen test cases this question
