The process consisted of 5 rounds:

• Online Assessment on HackerRank (2 coding problems)
• Technical Phone Screen 1 – Data structures and algorithms
• Technical Phone Screen 2 – System design and code optimization
• Onsite / Virtual Onsite (3 rounds):
  • Data Structures & Algorithms (Coding)
  • System Design / Low-level design
  • Behavioral ("Googliness", leadership principles, team fit)

Round 1 (OA):

• Find the longest palindromic substring.
• Design a rate limiter using concurrent goroutines (Go specific).

Round 2 (Phone Screen):

• Implement LRU cache from scratch.
• Time and space optimization for recursive Fibonacci.

Round 3 (System Design):

• Design a URL shortening service (like bit.ly).
• Discuss trade-offs between consistency and availability.

Round 4 (Behavioral):

• Describe a time you disagreed with a teammate.
• How do you handle ambiguity in problem statements?
