Deloitte Full Stack Developer interview questions

Got a call from HR after applying through their job portal. Collected information. Scheduled interview for round -1, Qualified. Scheduled another round in next week round-2, Qualified. Next round on the same day with different panelist, Qualified. Next day got a call from HR for final interview. I am selected as per their feedback and asked to wait for 2 days to get offer letter. After waiting from long time and too many calls, no response from them. I rejected other offers because of this.

They sent me a link to record the video, you can record the video twice and each record was around 3 minutes, they will ask some basic behavior questions, and I received the move on email next week.
