Nisum Senior Java Developer interview questions

Went through four rounds of interviews was offered with a very low hike, with stupid reasons such as cost of living in Hyderabad is very low compared to other cities etc. But anyways I was accepted the offer as I was on break for few months. And when I asked them to release the offer letter and was asked to submit documents which I did that day itself. And next I was told that my profile was on hold stating that we donot offer so much package and when asked for the reason for my profile put on hold to the HR he could give any satisfactory answer. Please look for unprofessional companies like these who donot care for time and effort invested by the person in the interview process. I would not recommend Nisum , and think working with them would have been more bitter experience, totally unprofessional behaviour on their part.
