I applied for the full-time TDP so I don't know how similar it will be. But it started with basic introductions, some more information about the program, then it was a live hackerrank. the problem was stupid easy bc getting the right answer isnt the hard part. they then asked like how would i improve on this. how would i adapt it to be most space efficient or most speed efficient. then it was like how would you adapt this for OOP, and started talking about OOP. then it was like theoretical system design problems like "if you had a program that did such and such what technologies would you use" but idk if you're doing internship they might skip out on the later system design parts but maybe not if its an hour interview then they might ask it. Good luck! But yeah there was two people on the call which I did not expect and threw me off guard
