I've interviewed people for roles as low-level C++/kernel programmers who did not know what hexadecimal was. Having a quick "What's 0x2A in decimal? Feel free to use paper & pen."[1] question can be a significant time-saver / direct people to more appropriate roles, if any.
[1] Starting to do math with non-base-10 numbers was already a pass, regardless of the number you reach, you'd normally use a computer for that. But it really isn't too hard to do in your head directly, for anyone who's dealt with binary data.
