EY Software Automation Test Engineer interview questions

I had given 3 rounds, all the 3 rounds went well they asked me programming questions and other questions based on my skills. but after 3rd round they didnt gave me any response.After every round there was a new HR connecting with me, so when after 3rd round i connected with HR he said he is not looking into it the previous HR spoke to me will update me, Since then i was trying to conect with HR she is not replying I event sent the Whatsapp messages to her but she didnt responded and just ghosted me. Its very unprofessional behaviour. they wasted my around a week and after that they did this.
