EY Manager AI/ML interview questions

I was short listed for a F2F round at Noida Office as part of recruitment drive. I cleared 2 rounds in f2f at noida. I was called for a virtual round. Interviewer had no idea why the interview was set up. Got a call from HR manager who offered 60% of my current salary even though I had declared my CTC at screening. Waste of time. 1.5 month gone
