A software engineer? Sounds totally unreasonable. A mechanical engineer, sure, it's going to be required material on their education.
The tortoise and hare algorithm is not the foundational skill required to make software work the way an understanding of motion is for building structures. That's why it's often omitted from educational material yet these people are able to produce usable software after even something like a bootcamp (which I guarantee basically no bootcamps ever touched this algorithm).
I'm not sure I approve of asking even more well known algorithms like Djikstra's algorithm or A* in a job interview, unless the role was something that specifically required that area of knowledge like building pathfinders for video games or robots or something.
