Can confirm! I also interviewed 2/18 and they said 3-4 weeks! My interview was way different than yours! The interviewers asked us broad questions initially and each of us interviewees answered in different orders for each question. We kind of bounced around with conversations based on each of our answers but I don't think the interviews asked any of us different/separate questions (I kind of wish they did tho because I feel like a lot of our answers were similar but worded differently, so it felt like whoever answered first was kind of in the "hot" seat in a way, having to come up with an answer without much thought).
