EY Software Developer interview questions

The process was very smooth. The interviewer was very friendly. Who process was timely and good. There were two rounds, technical and HR. The HR was a telephonic interview while the technical one was on Microsoft Teams

The first round is an automated video call for mainly checking your communication skills,second round is an online test which consists of aptitude and it was held on AMCAT. Third round was a technical interview where the interviewer asked questions on trees,sorting,etc.Fourth round was HR roundwhere HR asked basic questions and he said that he will roll out an offer. Then,suddenly I got a call from the hiring manager and he said that this is not an evaluation round and it's just to check in which team you would fit. But then after some days when I called them back,they said that they have rejected me. This was the worst interview experience ever and I never expected something like this from a company like EY.This is highly unprofessional.
