I had applied for AMEX in campus recruitment. The first round was consisting of 50 MCQ questions(30 coding MCQs and 20 Apti MCQs) and two coding questions. On the basis of round 1, they shortlisted almost 13-14 candidates for technical round. they asked a few programming questions and about CV projects. after this, they called for HR round and finally they shortlisted 6 candidates.
