One video interview. The interviewer seemed very disinterested, never had their camera on and just didn't seem like they wanted to be there at all. Three section interview on Linux, Git and Vim. I thought the whole section on Vim was very weird

Very Smooth. HR is extremely responsive. Interviewers asked mostly behavioral questions / technical questions about my resume. My advice is to review your resume, understand the roll you're applying to and how it serves the goal of the company.
