The first three rounds were suspiciously easy. No behavioral questions nor any difficult questions were asked. Small company trying to sell you on why you should work there. Fourth round; below reports of a panel interview are correct (5+ people). Exercise directions are intentionally minimal/vague, leaving your proposal entirely open to interpretation. Prepare to spend 10-15+ hours on a powerpoint and in-person presentation for the potential/likelihood of getting rejected. I'll save you some time interpreting their business model; their revenue is primarily from reselling paint. Proposed salary bands are very low, they offer zero equity, no comprehensive bonus plan, and one day wfh. Based on employee turnover of less than a year, this might be a great role for kids out of college or those looking for an interim role during the tech recession.
