1) Recruiter phone screen, 2) hiring manager phone screen, 3) half-day onsite, 4) homework assignment, 5) another half-day onsite + homework assignment presentation Positives: Scheduling, follow-up, and overall coordination were done well. The interviews are very structured and focused, so candidates are likely being compared against a standard set of metrics which is good to see. Negatives: Extremely time intensive. Not very welcoming or friendly; a sterile/mechanical vibe. But, by far the biggest negative is how Grammarly handles the homework assignment. They set off several red flags that they could be exploiting candidates for free labor and fresh ideas. First, the assignment asks the candidate to work on a problem that Grammarly is currently trying to solve and that directly impacts the business. Wouldn't a hypothetical be more appropriate? Second, the scope of the assignment is unreasonable for an interview. Anything that requires more than 3 hours of work to do a good job is not cool. Third, they requested a copy of my work after I presented. Again, this is inappropriate. The candidate is not in a position to refuse and leaving a copy behind was never part of the process explained. It's possible nothing shady is happening here but these are hallmark signs and left me feeling very uneasy about what I invested.
