Intro call with recruiter. Technical with team member. Data challenge. Onsite. Onsite was one of the worst I've had. Mathematical whiteboarding was in one of the interviews even though I was told this would not be a part of the process. The questions were not outrageous, but not something I've looked at at all in 2 years. After not doing well on this particular interview I was shown to the door with no explanation after being told "we will follow-up". There was no follow-up and I was totally ghosted. I'm glad I had this experience because I wouldn't want to work for a company that represents themselves in this way.
