I attended the interview for 3 days.
Day-1: Telephonic Interview (Technical)
Day-2: Written Test, Technical Round, HR Round, Managerial round (Done all the rounds and spent more than 4 hrs)
Day-3: Called me for Salary discussion and I went to the office, They offered me less than my present salary. They wasted my time and money.
I request ITP, Please don't waste job seekers's time.
