The interview process was really simple. After submitting my application in the online portal I was contacted directly by the PI in the lab I applied for. We spoke for about an hour and then after receiving my references they submitted to HR for an offer.

Applied for the position, was contacted a few weeks later by the PI's assistant for an in-person interview. Was a small lab so spoke with just the PI and 2 post docs. Received a request for references at the end of the interview and was given an offer within a few weeks. No room for negotiating salary due to grant constraints.
