Nagarro Sr Developer interview questions

I attended 22nd April drive at Bangalore for position of Sr software engineer.Its 4 round process. 1)Online test. 2)Face to face first. 3)Face to face second 4)HR As per HR feedback it was +ve and they would contact me on Wednesday 25th April but I didn't get any of call any mail from HR department . I request to hr people please update the candidate either he/she selected or not or in queue.

Although the interview process was very good, but I still did not get the offer letter. Me and my were called on a saturday and we gave a coding test and 2 technical interviews. After that, next day I got a call from the HR saying that your friend has been selected and you need to give an another round. I went back to the location and gave one more round which was kinda good too. The next day the HR calls and says that you have an 80% chance of converting,meanwhile you prepare certain documents which has to be submitted like aadhar card, pan card details etc. It has been almost a month now and me and my friend both have not received anything. We messaged the HR lot of times asking about the status and everytime he says either 1 more week or 2 more weeks. Then one day he told that the position for which we were considering you is on hold and then a week later these people are coming to bangalore again to hire people for the same position. If any nagarro official reads this, please grab some courtesy to tell the candidate at the first place whether he is selected or not. Lying about this continuously for weeks does not help.
