After completing the application, there is an online coding assessment. If you pass that, you move on to two live 1-hour technical interviews with two software engineers at the company. The final round is another 1-hour coding interview and then a "reverse" interview.

Spoke with recruiter at uni career fair, received OA a day later. OA was a mix of coding and MCQ questions. I don't remember exact details but the questions were not too tricky and there was enough time. Basic multi-threading and parallelism knowledge was helpful. Received first round interview invite on the next day that I completed OA. Two 1 hour interviews. 1 was concurrency and 1 algorithmic/data structures. Received final round invite one business day after. Final round was 1 hour interview and kind of object oriented/design. And half an hour "reverse" interview where I could ask the interviewer any questions about the company. Very fast turnaround times and helpful, knowledgeable interviewers and recruiters. Got a very good impression of the intern program. Also, don't be afraid of concurrency interview.
