You'll get a string with *, -, and + characters, and its length is a multiple of a given number (sub-string length). Your task is to write a function to hash this string. The hashing algorithm works like this: first, split the string into sub-strings of the given length, starting from the left. Then, figure out the weight of each sub-string, where weight is how many times a unique sub-string value shows up after splitting. After that, sort the unique sub-string values based on their weight, from highest to lowest. If any sub-strings have the same weight, sort them by character order: * comes first, then -, then +. Finally, create the hash by sticking together the sorted list of unique sub-strings and return it.

The interview focused on data structures like arrays, strings, and linked lists. It was important to have a good grasp of Java fundamentals, number systems, sorting algorithms, and common data structures such as trees, HashMap, ArrayList, LinkedHashSet, Map, and LinkedHashMap. Having solid foundational knowledge and practicing coding exercises helped me do well in the interview.
