WTW Inernship interview questions

The internship I applied for was a software development internship. The interviewing process was good. First you complete the personality and math test, then you have to write a small piece of code to solve the problem they send you. If you do well, you get invited for an interview. You have to prepare a presentation about a topic they give you in advance. The presentation was only in front of one person, which seemed to be very interested and welcoming. After this, you get the proper interview, where one person asks typical interview questions and the other is asking about the code you sent before. Overall, the company is really nice and I'm happy I accepted the offer

Was an online video interview. 4 questions with 2 minutes to prepare an answer and 3 minutes to provide one. No retakes allowed. Annoying because they worked on a first come first served basis for applications so received an email 30 minutes after my video (clearly not enough time to review/ discuss it) saying they'd filled all the places.
