This could be outdated information that I have, but don't actuaries constantly need to study for their exams/certs? Does that fall outside of the 40 hour/week range, or is that done on work time?
There's also a career-long continuing education requirement that typically boils down to 15 hours/year of seminars or webcasts, all done on company time.
Even if you are fortunate not to have to do leetcode (i.e. frontend engineer interviews seem to diverge from leetcode problems nowadays), you still have to extracurricularly grind on coding in ways that you would typically not encounter during your normal work.
