he Google intern interview process is rigorous and typically consists of one or two technical phone or virtual interviews. Candidates are assessed primarily on their problem-solving skills, coding ability, and understanding of data structures and algorithms. Questions often involve arrays, strings, trees, graphs, dynamic programming, and complexity analysis.
Interviewers look for clear logic, clean code, and strong communication—thinking out loud is encouraged. Some behavioral or situational questions may be included to assess teamwork, leadership, and motivation. Preparation using LeetCode, HackerRank, and Google's own resources is highly recommended.

Question 1
Given a string, find the longest substring without repeating characters."
Easy two interviews, one difficult one with a vice president. The first two were easy technicals then some behavioral questions and the final round was kinda hard with more questions and lot of personal stories and experiences.
There was a behavioral screening phone call followed by two rounds of interviews. Each round had two technical questions and some more behavioral stuff. The technical questions themselves weren't too difficult but the interviewers pushed for extremely optimized solutions so it was quite challenging.
