Your question is Geohashing Implementation. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you implement geohashing?
Explain and implement a production-quality geohash encoder for latitude and longitude. Your solution should convert coordinates into a configurable base32 string, decode a geohash into an approximate bounding box, and support neighboring cells for radius or map-tile searches. Discuss precision, boundary effects, invalid coordinates, and how geohash strings can be used as categorical or spatial features. Include tests and concrete correctness and performance metrics.
