EPAM Systems Software Developer Sr interview questions

Worst experience ever. There were 2 rounds, 1st technical and 2nd managerial. I got call from HR saying I got selected and company can offer XYZ fixed compensation and asked me to submit some documents. After 2 days I got call saying there is another Project interview round. Interview went well. After interview I got call saying they will release offer letter by EOD. But I didn't get offer letter. I was trying to call HR but my contact got blocked by them. Being a professional IT company this kind of behavior is not acceptable at all. This is the way the are behaving during interview process then how they threat employees after on-boarding?

Worst process, recruiter Sandeep Pittla is the worst recruiter. while discussion they ask you salary details and all, then after crack the interview they will say we cannot give you even 30% hike. No Laptop Worst process and Sandeep Pittla
