Async technical assessment. Doesn't require any commitment on their side, and provided no feedback after rejection. Prestigious company so they can do it. Bummed to not move forward. Technical questions were simple but interesting enough.

Straightforward and professional. First recruiter call, set up with automated calendar slot selection. Then set up for first technical round. Interviewer was nice and professional. Did not get the job as my stats knowledge did not cut it, but for someone with good stats background I think would be easy. Anyway, was a good experience.
