1st round is to be self introduction with HR theymight check you communication level 2ND Round is to be communication test with customer and ability to solve customer problem 3 rd round is to be manager round

It consists of 3 rounds 1.HR Round to test our Communication skills, 2.Assessment round to know the Analytical and problem solving skills, 3.Manager Round Overall my experience is good because for every round they are shortlisting so it won't take time to select for final round
