I was contacted by email and set up an initial 30 minute phone interview, with little wait time between initial contact and phone call. About two weeks after the I received a coding challenge invite.

One technical screen to solve a coding problem, followed by a one-on-one technical interview about a week later. Full day virtual on-site another few weeks after that. This included a mix of some live coding problems, some question and answer stuff, and a social hour. They sent a lovely gift basket to enjoy during the social hour. Great interview process, and the "onsite" was really fun and low stress.
