Deloitte Senior Software Engineer interview questions

Easy to difficult . Level increases gradually here. 1st was a telephonic round and asked about previous organisation,roles and responsibilities of mine there,the project,tech stack I used there. The cloud platform I was using and any certification if i have done

The interview was of 3 rounds, 1. Call with Hr 2. Technical F2F 3. Managerial After managerial didn't get any feedback even after following up with hr through mail and calls . It took almost more than 45days. I got reply saying I have rejected the offer. They scheduled another round of technical interview After I reverted saying I am interested in the profile and haven't rejected any offer. And yet again no response. No more interested for this profile now
