First an online OA, which was mostly probability and stats but also some other questions, then one interview then 3 interviews in one day all of which were probability, stats, brainteasers.

- Approached by recruiters - Remote math test, high school math questions, stats. Sample test available online - Triage, mainly brainteasers - Focused interviews Seems they pay quite well for what they do. I guess there may be some ethical concerns surrounding the company which they compensate for e.g. concerns about right wing political connections/ donations, previously suing employees, siloed working due to secrecy etc. The interviewers were particularly rude, arrogant and did not seem to understand basic concepts. Lots of red flags.
