I found out about the job through a referral and was fast-tracked through to the onsite stage.

The bulk of the interview was four hours of dehumanizing, humiliating, and frustrating whiteboard coding exercises conducted by different members of the team that was hiring.

There was very little focus on the company and what it is like to work there, or cordial interaction; just grueling hours of back-to-back writing on a whiteboard.
