EPAM Systems Middle Software Engineer interview questions

I gave many interviews but EPAMs recruitment is the WORST WORST WORST. They show that withing 10 days they'll complete the interview but almost more than 1.5 month took to complete my interview process to complete . 1st round General interview: where HR will inform u about the process. That after this there will be a technical round for 1.5 hour and then a manager round and then the offer. I cleared the technical which was quite hectic interviewer wasn't agressive but asked so many questions and I even had to code multiple coding questions. So,i was informed that i am selected for manager round. I gave the manager round,i was selected, Then they said and i quote "UNFORTUNATELY THE POSITION U APPLIED FOR WAS ALREADY FILLED SO WE WILL HOLD UR CANDIDATURE" now after 15-17 days i got a call from HR that A new requirement has come and i quote again "WE WILL BE OFFERING YOU (XXX LPA) GIVE ME 2 DAYS AND WE WILL SET UP A MEETING TO DESCRIBE THE COMPENSATION" //after 2 days// I quote again " ACTUALLY WE WONT BE RELEASING THE OFFER NOW BECAUSE MANAGEMENT WANT TO CONDUCT ANOTHER ROUND OF INTERVIEW TO DOUBLE CHECK UR KNOWLEDGE ON JAVASCRIPT" //Just to inform u all EPAM records all of its interview round// Now I had no option other than accepting the new unwanted round This time interview was very agressive and It was a complete hard core coding round he came and pasted a 20+ lines of question to code. And i even answered correctly one of the event loop question which he said was wrong and eventually i ended up losing up the offer. And the HR has no answer to it. I have all the proof of email communication regarding discussion on the process of interviewing . SERIOUSLY EPAM HAS A PATHETIC RECRUITMENT SYSTEM I WISH I COULD GIVE -VE RATINGS
