The interviews are all one way video interviews, where you are expected to record answers to some number of questions (many of which overlap with written questions they handout separately). They will send you a form to submit.

Based on my experience this year, you have to answer some questions via typing and recording, which are not difficult. The recordings can be attempted as many times as needed. Then, you are probably invited to a call with 100 or so other people who did the interview. This basically means you can get the internship. In the actual words of the Vosyn recruiter in the call, you should get a second opinion on this oppurtunity and consider if unpaid work for a startup like this is in your best interest. I declined.
