American Express Software Developer interview questions

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.

There were four rounds. First was an online test, other three were interviews. There were two technical interview rounds, and one HR round. Mainly they asked questions DBMA, specially joins.
