American Express Interview Experience for Software Engineer Internship + FTE | On-Campus

American Express visited our campus in August 2021 for the position of Software Engineer Trainee at the Gurgaon/Bangalore Location. There were one coding test and 3 interview rounds for selection in the company. The CGPA cutoff was 7.

Online Coding Test: Online test was conducted on Codility which comprised 3 coding questions that had to be solved in a duration of 1hr 30 min. The disadvantage of this platform is 80% of the test cases are hidden and are run in the background. So you can see your code running on only 2-3 test cases and it is very difficult to figure out whether the program is correct or not.

Tip: Try to solve at least 2 coding questions correctly.

After the first round, approx 30 students including me were shortlisted for the next round which was an interview round.

Technical Interview Round 1: This round was a technical interview round. The interviewer asked me to give a brief introduction about myself. I started my introduction by telling most of the things that were written on my Resume. Then he asked me the following questions:

Tips: If you have done any internship or certification course then prepare the question from that too. Be thorough with all the core computer science subjects because the interviewer may test your knowledge in any of the subjects.
