Appearing for a 3rd round interview in Deloitte USI

I’m not sure about which community to post this, so leaving it here. I’m being interviewed for a consultant level position at Deloitte USI. I have cleared 2 rounds and one more interview is scheduled in a couple of days. I just want to know whether the interview will be technical or managerial and are there still chances of being rejected. Will it be a casual discussion or is it an actual interview?
