The Google interview process is a rigorous, well-structured pipeline designed to identify top talent for one of the world’s leading tech giants. It typically unfolds as follows:
  • Resume screening
  • Recruiter call
  • Online Assessment (OA) (Usually 2-3 LC DSA questions)
  • Technical interviews (Typically 4-5 rounds, covering DSA, system design, and sometimes domain-specific knowledge)
  • Behavioral interview (Focused on Google’s culture and “Googleyness”)
  • Hiring committee review and decision
To prepare effectively, focus your study plan on three core areas:
  • Data Structures & Algorithms (DSA)
  • System Design
  • Behavioural questions
1. Data Structures & Algorithms (DSA)Google is famous for its love of algorithmic problem-solving, often pulling from LC-style questions. The most efficient approach is to study the most frequently asked problems, prioritizing medium and hard difficulty levels. Efficiency matters: Aim to solve problems in 20-25 minutes during practice, with optimal time and space complexity.Communication is key - interviewers expect you to articulate your thought process clearly, from brute force to optimized solutions.
2. System DesignSystem design interviews at Google often focus on massive, real-world systems tied to their products—like designing YouTube’s video streaming or Google Drive.
  • Expect deep dives into scalability, latency, and availability. Interviewers may ask about trade-offs between consistency and performance or how to handle billions of users.
  • Key concepts to master: distributed systems, caching, load balancing, and database design (SQL and NoSQL).
  • Practice sketching architectures on a whiteboard and explaining your reasoning - clarity is as important as technical depth.
3. Behavioural questionsGoogle’s behavioral interviews assess “Googleyness”—a mix of cultural fit, curiosity, and adaptability. Questions often tie back to their values, like collaboration and innovation.Practice using the STAR method (Situation, Task, Action, Result) to structure your responses concisely.Common themes include:
  • Problem-Solving (e.g., “Tell me about a time you tackled an ambiguous problem”)
  • Teamwork (e.g., “Describe a situation where you resolved a conflict in a team”)
  • Growth Mindset (e.g., “Give an example of when you learned something new to solve a challenge”)
Luckily for you we’ve already done all the heavy lifting of compiling the list of most frequently and generating solutions for each of the above 3 categories.
