Google – Overview
Google Overview
🏢 What Is Google?
Google LLC was founded in 1998 by Larry Page and Sergey Brin while they were at Stanford University. Since then, it has evolved from a simple search engine into a major global technology company. Its parent organization, Alphabet Inc., now oversees a broad portfolio that includes Google Search, Android, YouTube, cloud computing services, hardware products like Pixel and Nest, as well as innovative projects in autonomous vehicles (Waymo), biotechnology (Verily), and space exploration (Lunar XPRIZE).
Known for its data-driven innovation and ambitious “moonshot” projects, Google serves billions daily and pushes boundaries across industries.

Google’s Hiring Process
👶 Freshers & New Grads Recruitment
Google hires new grads extensively from universities and internships programs. The typical process includes:
- Online or Recruiting Fair Application: Resume screening + referral or application
- Online Coding Assessment: 2–3 coding problems in Java, C++, or Python using platforms like Codility or HackerRank
- Phone/Virtual Technical Interviews: 2–3 rounds focused on DS/Algos, System Design basics
- On-site Interviews: 4–5 on-site interviews including coding, design, and behavioral rounds
🏆 Experienced Professionals Recruitment
Lateral hires follow a similar pattern, with more domain-specific interviews and deeper system-design discussions:
- Resume & coding screening
- Coding & system design interviews
- Leadership and product interviews
- HR/manager interviews to assess fit, career goals
📈 Coding & Exam Difficulty
💻 Sample Code Snippet: Longest Increasing Subsequence (Python)
def length_of_lis(nums):
from bisect import bisect_left
dp = []
for x in nums:
# Find index to insert/replace in dp to maintain increasing subsequence
i = bisect_left(dp, x)
if i == len(dp):
dp.append(x) # Extend the LIS
else:
dp[i] = x # Replace to keep dp minimal
return len(dp)
# -----------------------------
# Example usage
# -----------------------------
if __name__ == "__main__":
arr = [10, 9, 2, 5, 3, 7, 101, 18]
result = length_of_lis(arr)
print("Input array:", arr)
print("Length of Longest Increasing Subsequence is:", result)
📚 Aptitude & Logical Rounds (where applicable)
While Google primarily focuses on coding and design, some roles may involve product or analytical tests requiring logical thinking and model-based problem-solving.
📝 Essay & Written Communication
For roles in policy, research, or product management, candidates may submit design documents, essays, or conduct case write-ups to demonstrate thorough thinking and structured communication.
🧩 Technical & Behavioral Interviews
- Coding: DS/Algos questions requiring efficient, clean code
- System Design: For mid–senior roles, expect large-scale design (distributed systems)
- Behavioral: Leadership, teamwork, conflict resolution, Googleyness
