Online Coding Assessment. Aced it but they didnt contact me after. It was about 2 hours long but I took 1 hour. Got the rejection notification a couple days later.
Codility online assessment was the first round which was leetcode style. Then a technical interview and then a superday. Technical interview entailed multiple questions on various topics such as algorithms, data structures, os, networking, system design and more.
