Pretty typical process - hiring manager 1:1, portfolio review 1:1, (virtual) on-site. There were lags in between, so my advice would be to be patient. Not all hope is lost if there are delays in scheduling follow ups, especially during this time (pandemic).

A zoom call that lasted 30 minutes with one of their staff researchers. They said I would present a research project but that was 2 weeks ago and I followed up with my personal recruiter and have not heard anything so my guess is that they moved on.
