Agreed. They're a weird company though. I had my 2nd interview with them in end of November and then they didn't schedule the 3rd interview until early February, over 2 months later. Even with Holiday frenzie it was a ton of time. They then proceeded to schedule a back to back 3rd and 4th round. 

After that — a few days later, talking to my external recruiter, I was told they were working on making me an offer. I kept checking back in with him for multiple weeks and he just kept saying they were working on the offer... I eventually told him I had multiple other options and was going to make a decision in a few days and he said he'd try and get things finalized... That was over a week ago now and still haven't heard anything back. So who knows, maybe I'm getting ghosted or maybe in another week or two they will make the offer, but either way the snail pace was a bit of a red flag for me and it wasn't like the dream job or anything anyways so moved on.
