Google Software Engineering interview questions

Two technical phone screens. First was just one question, string parsing to make a larger string based on the contents. Big focus on testing at the end. Second screen had multiple questions, how to store a file system in a data structure (Trie). Implement the class for this.

Stage 1: online coding test. pretty easy questions. timed. Stage 2: 2 technical over the phone interviews. typical leetcode/algorithms/data structures questions. Stage 3: Host matching. finding a project to match the intern to.
