Cron-J interview questions

It was automated interview. The interview was held on AL Interview tool named Birbal. I have given 2 rounds of interview and got the call that I am qualified in the 2nd round and They will send a mail for 3rd round. But the 3rd round of interviews never happened. The company is now not answering my calls or message. It's very unprofessional behaviour.

Attended 200+ interviews in a span of 3 years but this is the first time & by far the worst experience I've ever faced. Just lost total interest. The product used for interview , Birbal AI (probably inhouse product) ,the most pathetic form of interview process. Company and product go hand in hand.
