American Express Software Engineer(Internship) interview questions

It took an hour to complete. I was very tired at the end. There were two interviewers and we spoke through HireVue. They were friendly but not very helpful. I had 3 coding questions, a few behavioral questions, and like 2 technical questions. The questions were not difficult. One of them is about binary trees but not a hard level. Others were also easy but tricky. PS: Be sure to always speak to show your thought process.

The entire procedure contained 1 online coding challenge and 3 interview rounds. The coding challenge was fairly interesting but the main focus of the interviews was on oops, projects, real world applications of technologies and general aptitude. Coding questions in interviews were very easy. Some simple puzzles were also asked.
