Jubilant Biosys interview questions

Two rounds are there. Interviewer are cooperative. Gives time to answer. Overall experience is good. HR is very supportive. In technical round, they give u the option to choose out your best from which they can ask you a question.

The interview process was smooth.It all began after the interview.I was told that I am selected and join with 14 days,they will send a mail regarding further process.But the HR vanished afterwards.NO RESPONSE. I CALLED ANOTHER HR, she told me she will get back to me. I again mailed them after 3,4 days. They replied saying hiring is done. They could have informed me that I am rejected. VERY UNETHICAL!
