Robinhood kept the interview process really straightforward. There was an initial recruiter call, followed by a technical screen. After passing that, I was transitioned to a different recruiter for the rest of the process. Because the entire world is working from home right now, I had a "remote on-site" for my final interview (basically a 5-hour Zoom call). Despite the technical hoops, everything felt pretty seamless, and I feel like the team and I got a good grasp of each other. The engineers were all really clear communicators. The process focused more on seeing how you approach a problem and react to new information, rather than having the most perfectly optimized solution.
