I work as a data scientist, and my graduate research involved harmonic analysis over compact groups, optimization over Riemannian manifolds, and loopy belief propagation. You'd reject me in an interview because I couldn't remember the formula for standard deviation off the top of my head?

It's not a hard weed-out for us. But, if you talk through variance for 10 minutes, you get pretty close to the formula for standard deviation.

Also, for our role, we're specifically hiring someone with extensive stats background since a large part of the role is learning domain-specific statistics of the industry we're targeting and figuring out how we can adopt those models with our data.

Personally, I don't ask weed-out questions. Never have, never will. I'm just saying that's what they're doing.
