I recently went through a few phone rounds with Brave for an iOS Developer position and thought it might be useful to recap the experience in case you're in their sights for a similar role.
Founded by the disgraced (or vilified, depending on your political leanings) ex-CEO of Mozilla, Brave publishes a web browser alternative for mobile and desktop platforms. Based on a fork of the open source Mozilla source code, Brave's angle is that their browser is faster and you can "earn" tokens to "pay back" to websites you spend lots of time eyeballing. For their mobile teams, I remember them mentioning they currently have 4 iOS developers in total (two dedicated two the browser, two working on the BAT cryptocurrency-like scheme -- in other words, it's not a big team at all) and the same number on the Android side. Both engineers I spoke with were in dramatically different locations around North America, so Brave appears to fully embrace a remote workforce (and that certainly saves on office space & rent in the pricey Bay Area). I was especially attracted to the fact that the work an engineer does at Brave is all open source and public, which is a nice change of pace from the usual everything-is-proprietary-and-NDA'd way of doing things in the tech industry.
In terms of the interview itself: one iOS engineer was very friendly and clearly a potentially fun teammate. The other one seemed to have strong opinions about architecture and clearly didn't like my explanations as to his subjective (and open to interpretation) code sample. I've recapped the questions below to give you an idea of what to expect.
So all in all, this didn’t work out well for me due to a botched interview with one of the iOS engineers. Perhaps it'll go much better for you! Hopefully my experience flunking the interview process at Brave will help you to properly prepare for yours.
