They have a pretty standard technical interview schedule, but could use some adjustment to be respectful of their candidates. I suggest you follow along with the rest of tech and stop doing the lunch interview. Instead, give the candidate a chance to reset. Nobody is their best after being grilled for 6 hours straight. Unless you're looking for robots. You might be, and that's cool.

The interview process had the least "problem solving" and "coding" of any I've ever done. I am not sure how they could truly make any judgements on my coding ability or intelligence after it. There was only one question that required coding. For the first time ever, I was asked a question that was essentially just syntax and checking if I'd done a very, very specific CSS/HTML thing before. Those types of questions are pointless, but to each their own. Expect the rest of the day to be behavioral and situational questions.

My walk around the office during the on-site showed some pretty serious gender imbalance in their engineering staff. I appreciated getting feedback from my recruiter on why they chose not to extend an offer. That's rare, and very lovely! But some of that feedback was in line with my mixed impression after going on-site. Namely that they are a pretty male-dominated culture looking for a certain type of personality to fit in there.

Good luck in your interviews, friends!
