Initial 30 minute screening and discussion call, then a one hour interview with a supervisor/team lead, then a work assessment that can take up to 15 hours, then a one hour follow up discussion of the work assessment. The interviews themselves, though long, are straightforward and manageable. Everyone was professional and easygoing. The assessment itself is also straightforward, as it's largely just just using one of the company's software products and developing tutorial materials for it. There are some intentionally tricky sections and you're expected to ask questions if you get stuck. In fact, I was told that one of the reasons they ended up going with other candidates was because I was "too self-reliant" during the assessment.
