Grammarly uses what I have since learned is called "Topgrading" throughout the interview process. For this role, I had over 9 interviews spanning almost 8 weeks, the final week comprised of 5 interviews alone for the virtual onsite. The people were lovely, and I appreciated the opportunity to have a cultural-fit interview with people who would be my peers to ask more honest questions. They both spoke glowingly about the culture and offered that they found the interview process misleading in that working at Grammarly was actually a far more pleasant experience than the interview process portended. The topgrading method is meant to flush out people being dishonest. I don't love the idea that the company assumes dishonesty is the norm. I also found it a big red flag that I had to sign an NDA before completing the take-home exercise and that the exercise was about the company's own content (which I've been told is another red flag). If (when) my ideas appear within their product, I'll be pretty irritated. Overall the team seemed great and I would have been happy to work there if I had gotten an offer but I did see some signs of politics between different teams that could indicate the reality of working there is a little less rosy than staff portrays.
