Fibonacci Interview Questions

Find the distance from a given number to the nearest term of the Fibonacci sequence. This Meta question is a generate-and-compare exercise, and the growth rate is the thing that makes it easy: the terms climb so fast that only a few dozen are ever relevant. You will generate until you pass the target, compare the neighbours on both sides, and handle a target that is itself a term. A subscription unlocks the complete problem and the reference solution.

A coding question about generating every sequence built from two small symbols that meets an exact total, then reasoning about how large the result can get. It tests recursive enumeration, ordering of the output, and how to size the work by what is produced rather than by what is searched.

This reported interview question from WeRide challenges candidates to compute large sequence values efficiently without relying on standard linear approaches. Instead, applicants must leverage mathematical properties of linear transformations to achieve logarithmic performance. You will need to demonstrate strong algorithmic optimization skills to handle large inputs within tight constraints.
