2x interviews; 1x test (TSA)
First interview: maths-based; Second interview: personal statement, EPQ, coding activity

You don't need coaching to get in; don't stress about specific topics you might be asked
Remember this advice isn't official. There is no guarantee it will reflect your experience because university applications can change between years. Check the official Cambridge and Oxford websites for more accurate information on this year's application format and the required tests.
Also, someone else's experience may not reflect your own. Most interviews are more like conversations than tests and like, any conversation, they are quite interactive.

The Maths interview was literally only answering maths questions in front of 2 interviewers, and they didn't interact with me much other than asking me questions & occasionally prompting to say some more stuff about my answers. Questions were all quite nice, nothing overly complicated but if panicked could be tricky, but if you got stuck they'd help nudge you in the right direction.
Computer Science interview again had 2 interviewers. Asked a bit about some stuff on my personal statement about a taster course I'd been on etc. and also about my extended project. The rest of the interview was an extended coding task - you didn't need to have coded much before, since they let me write it in pseudocode since I didn't have much experience.
Nothing specific, but making sure I'd read any books I said I'd read! My school didn't organise anything to help, so I was going in pretty much blind.
You can get in fine without being specifically coached for it! Plus don't focus too much on what specific topics people were asked about previously since as I said my DoS makes sure to change the questions completely.
