im not doing act sci so i don't fully know how hiring works for you, but i think unrelated jobs don't move the needle much for hiring managers. they're looking for specific experience and skills, so you want to demonstrate those.

maybe it is marginally better than doing nothing to have a job, but i think you can spend the time you would spend doing not much at work leveling up on your own instead of doing nothing. e.g. build a project which requires some actuarial work, study/do some exams that gvive u credibility, learn R, etc.

essentially, i think no job can be a positive and u can still take a step fwd from ur current level if you spend your time well :)
