I applied through university. I interviewed at American Express
Interview
It was a 3 round interview: 1. It was a coding round with three questions of easy-medium-hard level each. 2. The next round was one to one interview round where questions related to OOPS, Linkedlist, and DBMS were asked. Along with that puzzles were asked(refer gfg puzzle). Also, some behavioral questions were asked. 3. Last round was kind of HR round and behaviour questions were asked.

I applied online. I interviewed at American Express
Interview
3 rounds, HR screening, managers interview, director interview,
mostly on your experience and your competency.
Some questions were repetitive. Took a few weeks in total. HR quite responsive. But feel like the whole process can be a bit faster.
