Got an email shortly after applying (~3 days) from the senior recruiter, scheduled a 30 minute intro video call for the following week. Went well and found out on the same day as this behavioral interview that I was moving on. The following week, another video interview but, now with someone on the Marketing Team. Went well and found out the next day I was moving on again. Another week, another video interview with someone else on the marketing team (that surprise, went really well!). For the 4th round interview I was invited to their NYC office to meet with 3 people (30 minutes with 2 of them, followed by 30 minutes with 1). I felt very good after this and waited to hear back on feedback or next steps. But for some reason I never heard anything back. Followed up 3 times with my HR point of contact over the following 3 weeks and never an email back.
