FizzBuzz covers a lot of (very basic) ground but adding memory manipulation is valuable. I ask a few simple string manipulation interview questions for embedded C developers as a weeder and the point is that we want to see how candidates deal with pointers and low level memory. There are other good follow-ups and alternatives you can build off this. Engineers with years of experience fail these questions all the time. Dealing with 'tedious' things like this is daily part of some developer jobs.
