Compose Support Engineer interview questions

The interview process consisted of a work sample, which took near 8-10 hours to complete. This was followed by a 4-hour 'workday' which consisted of hanging out and asking questions in Slack. This was followed by a written submission detailing what I learned in the work day. The process was alright, but they do not provide any feedback at all, as per policy. This can be frustrating. The interview process is 100% remote.
