I spoke with a recruiter over the phone who said they'd like to invite me in for an interview. I never heard back, so I reached out, and quickly heard back from HR, who told me the recruiter's contract had ended. I was invited into the very quiet office, where I met with a few people who would be my colleagues, then leadership. The whole interview was around two hours long. I was told explicitly that because of some upcoming vacation time, I would hear back a little longer than what would be considered normal, but I'd definitely be hearing back within a few weeks. It's now been about eight months of radio silence. I didn't follow up again after the thank-you email.
