Loop — 4 rounds, all on the same day

Round 1 — Coding (DSA) Interviewer was a senior SDE, very friendly.

Warm-up + behavioral:

• "Tell me about a time you took ownership of something outside your responsibilities."

Main question: Given a list of meeting intervals, find the minimum number of conference rooms required. I used a heap. He then asked a follow-up: what if meetings could be reassigned to minimize total idle time? We discussed approaches but didn't fully code it. He cared a lot about how I talked through edge cases out loud.

Round 2 — Coding + Problem Solving LP question: "Describe a situation where you disagreed with a teammate." Coding: LRU Cache implementation from scratch. I used a hashmap + doubly linked list. He pushed on thread-safety and what happens at capacity 0.

Round 3 — Behavioral (Bar Raiser) This was the toughest round — no coding, all Leadership Principles, very deep STAR-format probing.

Questions I got:

• "Tell me about a time you failed and what you learned."
• "A time you had to deliver something with a tight deadline and limited information."

The bar raiser kept drilling:

• "What was your specific contribution?"
• "What would you do differently?"
• "What data did you use?"

Have 6–8 strong stories ready with metrics.

Round 4 — Low-Level Design Design: Design a parking lot system (classes, vehicle types, spot allocation, pricing). Then he asked me to code the findSpot() and releaseSpot() methods.

Most coding questions were LeetCode Medium.

Common themes:

• Graphs
• Heaps
• Sliding window
• Hashmaps
• LRU/design
• System design
