Twitch Global Service Operations Engineer interview questions

Applied online through employee referal. Contacted by Technical Sourcer after a few days to set up a 30 minute video call. After that was set up with a 60 minute video call with the hiring manager and then invited into the London office for interview panel (5 interviewers, 1 hour each). Week or two later received email stating they were not proceeding further, no feedback or reasoning provided unfortunately.
