EY Data Engineer interview questions

Pathetic - Interview process. Profile was shortlisted and scheduled at 12:00 PM. I was on time . I waited for any updated approx 1 hour. HR came and took the CV, then she asked me to wait outside a cabin where a Sr. Mgr was already taking interview. I was suppose to be next. The last gut left but the Interviewer not even looked at me . He went to other cabin and started taking some one else interview. After this he went for lunch . No tea cofee was offered to us for delay. Next HR came and said to go for lunch. I went there. As i came back the interviewer started taking interview of some one else. Again I was waiting once it was over again no botheration no value. So I myself approached me "Sir I am waiting for interview." His reply was who said you to wait here I am not suppose to take your interview . Then HR and then that interviewer talked something and then he agreed to take interview. He said I dont know I have not shortlisted. He asked me only about work and he was about to leave and said ok leave for the day . Sorry Such kind of process is shame for EnY. Please do not join EnY
