I applied through a recruiter. The process took 4 weeks.
Similar to other candidate reviews, I was abruptly rejected after the take-home project with no indication of reasons. I spent a weekend and made the project as perfect as I could. I did all the optional tasks, pored over my readme to ensure my documentation was extremely clear, and got positive feedback during the review. My reviewer said things like "yep that is correct" and "I'm sure you'll be hearing from the recruiter about next steps". I was surprised to get an autogenerated rejection stating that my background is not a fit a few days later. I asked for feedback and received none. If it had to do with my background, they should have found that weeks earlier in the process. The entire process took roughly 4 weeks. With enough bad reviews, I don't recommend you interview with this company. There is a strong chance you will spend significant time interviewing and prepping only to be rejected with no feedback.
The questions included TCP vs UDP, scenarios about blocked or delayed telemetry, and designing services for communicating with satellites, et cetera.
