Spoke with hiring manager via phone, then again via video interview. Then had a second interview with the hiring manager and another senior staff member, followed by an interview with remaining team members. The hiring manager stressed the plan was to move forward as soon as possible following the December holiday and explained that the office would be closed the following week. After a few days I was contacted by an HR rep - asking that I complete a formal job application, which I returned the following day. I never heard from the hiring manager or HR again.
