There's an online assessment with IQ (problem solving and spatial reasoning questions) and personality questions, along with some clean code questions. The assessment platform takes screenshots to try to catch cheating so I couldn't use pen and paper and wasn't able to complete the section. I got a 96% percentile on the coding questions relevant to the job, but the spatial and math problem questions were more average. Not sure what these skills have to do with the job but I got a stock rejection a few days later. I have talked to recruiters at this company before who have reached out to me directly, but I guess the test is more important than that.
