🚗 Uber SDE Interview Experience (Platform/Backend Role)
Role: Software Development Engineer
Experience Level: 1–3 years (L1/L2)
Location: Bangalore (onsite) or Remote
Rounds: 5 (including recruiter)
📞 Round 0: Recruiter Call (30 mins)
Topics:
Brief background check
Tech stack discussion (e.g., Java, Python, Go)
Resume walk-through
Role expectations at Uber
Availability for interviews
✅ Tip: Be honest about your experience. If you’ve worked on scale, mention metrics (e.g., “handled 10M+ API calls/day”).
🧮 Round 1: Online Coding Round (Hackerrank / Codility) – 90 mins
Structure:
2 or 3 DSA problems
Mostly medium-hard Leetcode-style
Examples:
LRU/LFU Cache design
Modify a matrix in-place based on constraints
Dynamic Programming (DP with memoization)
Sliding Window or Segment Tree problems
✅ Tip: Know your standard patterns well — sliding window, 2 pointers, binary search on answer, and prefix/suffix optimizations.
🔧 Round 2: Technical Interview – DSA + Low-level Design (60 mins)
Format:
Start with a coding problem (~30 mins)
Move to low-level design (LLD)
Examples:
Implement a Rate Limiter or Parking Lot system
Coding: Interval merging, Tree traversal variant
Discuss REST APIs: How would you paginate? How do you handle retries?
✅ Tip: Speak while coding. Explain trade-offs like time/space.
🧱 Round 3: System Design (High-Level Design, 60 mins)
Asked:
Design Uber-like trip matching service
Design a scalable Notification Service
Scaling REST API for millions of requests per sec
Talk about caching, load balancing, data modeling
Focus Areas:
Microservice boundaries
Message queues (Kafka, SQS)
Consistency vs Availability
DB choice (SQL vs NoSQL), Sharding
✅ Tip: Mention real-world practices like rate limiting, retries, fallbacks, circuit breakers (Hystrix-style).
🧑🤝🧑 Round 4: Behavioral + Leadership Principles (Bar Raiser)
Pattern:
Tell me about a time you failed
Biggest challenge with a teammate or stakeholder
Decision-making under uncertainty
Ownership / bias for action scenarios

Long-term vision of team
Your preferences (IC vs leadership)
