EPAM Systems Senior Ssoftware Developer interview questions

I had an Initial call with recruiter who gave no idea and what to expect and scheduled a call for next round. I was scheduled a call with an Engineer, and after just minutes I felt his sole task is to humiliate me instead of get to know me.. Interview is for 1 hour and 30 mins, but interviewer cut shot my tell about yourself in less than a min by saying I don't care.. The recruited started to asked question and all of them are text book questions like explain the Architecture for X and so on.. When I said, i didn't know but I can write code and solve any problems and the interviewer started to laugh at me and murmured in Hindi.. I have 8 years of experience and no single question about what I knew and what I work on.. Seems the interviewer's sole task is just to humiliate me.. I hope that is just me, and I don't want anyone to have the same experience.. I tried to reach out to recruiter to share my experience but they ghosted me.. I attended a good number of interviews, no one laughed at me for saying I don't know top a question.. I would never apply to this company again..

Too much interview, at least 4 round interview. 1.) HR interview 2.) tech interview 3.) manager interview 4.) hackerrank interview And after you pass all the interview, they will get ferfback to you after 1 month, and they say there are client interview. Why need to use a lot of time ? After the client intervirw, they also said they have another interview later too.... For people who really finding job, i think you should not consider this company, let go to apply another company is better for you
