Questions About Robinhood iOS VO Interview Process

As the title says, is there anyone who has recently interviewed for Robinhood iOS VO? I searched through the forum but there are very few iOS interview experiences, mostly backend ones, so I have to make this post to ask orz

Mainly want to know:
1. How many rounds does the VO usually have, and what is tested in each round?
2. What kind of tasks are given in the coding round? Will concurrency be tested?
3. Is the SD strictly focused on mobile? What kind of questions are generally asked?
4. Do they ask standard iOS questions? Are there requirements regarding UIKit and SwiftUI?

Please share whatever you know. If you have links to relevant interview experiences, please share as well. Any helpful replies will be rewarded with rice 🙏

Thanks in advance to all the experts!
