Applied beginning of December, interview request only mid January, offering exactly one afternoon (their time) / (late) evening (my time) in February. Eventually had a call on relatively short notice on a Saturday evening. I declined the second interview request because the position was fully on site, no options for fully remote working.

2018 Interview Process: The interviews consisted of phone calls with the sponsoring professor about my background and what the project they were working on was. Followup phone calls with current/former post-docs and students in the professor's group again concerning my background. On-site interview consisted of programming on a blackboard and meeting with the current graduate students, post-docs and professor.
