Nagarro Senior Developer interview questions

Total waste of time I gave mcq,coding round and then 3 techincal rounds and cleared all and got call from HR that i have made it to Naggaro.After a week she called me again saying you need to again give a tech round for html css. Is it some joke going on seriously i mean.It was totally a rejection round. Will not recommend anyone to join naggaro. Even after giving 4 rounds of tech interviews they did not see the capability of a candidate then they are just wasting your time.
