The first round was a coding test on codility comprised of 3 questions. Then, there were 3 rounds. 2 technical and 1 HR. My first round was very weird. As, he had touched almost all the concept. Even those that were not in my CV. He asked about java, OS, DBMS, Cloud, Backend etc. Then he asked me to devise a solution for searching on Google. I solved it using Trie. And, cleared this round. In second round, He asked about my project and had given a question of stack. In final round that was HR, he asked couple of questions like tell me about yourself, why amex etc. Overall it went well. But, I didn't get selected.
