There were two stages of the interview process. FIrst was with someone from HR and really friendly but professional. The second part was carried by would be immediate supervisor, although it wasn't framed that way, and the person was a touch too casual during the meeting (I get working from home, but minimum effort would go a long way). All of it was fully remote via Zoom and all communication other than Zoom meeting was via email. Overall quite clear process with really good communication from HR, but slightly lacking in professionalism on emploee/would be supervisor side.
