Applied and Interviewed with the Video Services team out of San Jose.
Applied online, and got a technical phone (Zoom) screen scheduled within a few days (very fast turnaround). This was a standard coding test (think Coderpad) for 45 minutes.
After passing first round, I was asked to schedule time out for 4 hours of interviews with the main team - I was able to split this into two days of 2-hour interviews (to accommodate my current schedule) which was very helpful. Team was very nice and I enjoyed the discussions and questions. Questions were a mix of personal experience, technical (Leetcode-style) questions, system's design questions, and good object-oriented programming practices questions. The interviews felt collaborative, with a lot of back-and-forth going on between myself and the interviews, which was VERY welcome. I've had a lot of interviews with companies where you are asked a question, only to be ignored by the interviewer until you state you have the answer ready, and Roku was definitely NOT like that, which was nice.
Special shoutout to Michelle, the technical recruiter assigned to me - she was very responsive to all my questions, and didn't hesitate to jump into a call for any concerns I had. She was both personable and professional, and made the post-interview experience smooth and easy to understand.
My experience with the team was positive, and I ended up accepting the offer provided.
