SoundCloud Senior Software Engineer interview questions

I applied from another country. After talking with the internal recruiter I was given a take-home assignment dealing with TCP servers and clients. Was able to build and work on it in the language of my choice. After this I met with two engineers to discuss my solution and to extend it by pair programming via video call. After this, maybe a week later, I met with someone from leadership for an hour via video call. The final step was an all day onsight. SoundCloud flew me out and conducted several interviews, many with engineers, whiteboarding architecture, product manager, etc. etc. etc.
