It is infrequent!
Author here: I knew enough C and Fortran to turn in small assignments for my physics courses, but Julia was the first one where I started developing code.
This is fantastic! I think that Julia really has unseen potential for the scientific community, and even more unseen potential beyond that (most of Julia conf is scientific).
FP also comprises of some really great habits to pick up early on, I'm still trying to unlearn dumb OOP idioms (which is why I'm targeting Julia as my next language).
Just the interview? Or anything language related?
