CMiC Intermediate Java Developer interview questions

Worst Interview Process Ever- Wasted my 2 months I applied online in Nov 2021. In the first round, HR sent me online test and I cleared it. After 7 days HR scheduled technical round after which there was another technical round after 15 days. After clearing that too, HR told me there will be one more technical round. I cleared out that too but I didn't hear back from CMIC for next 20 days. When I e-mailed them about knowing my feedback, HR said I have cleared all rounds and now final round will be with COO and CTO. I cleared this round also but HR called me after 15 days and started negotiating on the salary to which they had agreed before the interview process started. Still, I agreed and no response from their side till now. Completely wasted my 2 months and didn't provide any feedback too even after clearing more than 5 rounds. Start respecting others time.
