How to Crack the Uber Interview and Land a 70+ LPA SDE Job (Real Interview Experience & Strategy)
Why Uber Is One of the Highest Paying Tech Companies
Uber is not just a ride-hailing company anymore. It is a massive global technology platform that processes billions of events every day. That is why it pays some of the highest salaries in the industry. For SDE 2 roles, compensation often crosses 70 LPA, and for L4 positions, total CTC can go beyond 1 crore. With that level of compensation, Uber looks for engineers who can think deeply, design scalable systems, and write production-grade code.
This interview experience shows exactly how Uber evaluates engineers at this level.
How the Uber Interview Process Is Structured
Uber follows a multi-phase interview model. It starts with algorithmic screening, moves into deep coding and low-level design, and ends with high-level system architecture. Every phase is designed to test a different layer of engineering maturity.
Phase 1 – Screening and Core Algorithms
The journey begins with a CodeSignal test. Candidates are required to solve two coding problems with 100 percent accuracy. This is not about partial solutions — Uber expects clean, complete, and optimized code.
After this comes the technical screening round, which focuses entirely on DSA. One typical question asked here was a dynamic programming problem: finding the minimum number of times a string needs to be appended to itself so that another string becomes a subsequence. Solving this required both algorithmic insight and careful edge case handling.
I explained the recurrence, handled overlapping subproblems, and justified the time complexity before writing any code. That explanation mattered just as much as the solution.
Phase 2 – Deep Dive into Coding and Design
This phase had two interviews, each testing a different dimension of engineering.
The first interview focused on advanced algorithms. Two complex problems were asked. One was Cheapest Flights Within K Stops, which requires a combination of graph traversal and dynamic programming. The other was Maximum Points You Can Obtain from Cards, which relies on sliding window and prefix sum techniques.
Before writing any code, the interviewer insisted on a clear discussion of time complexity and space complexity. Uber wants to see that you can reason about performance before you start typing.
The second interview was all about low-level design. I was asked to implement a basic file system with APIs like mkdir, pwd, and cd. The real challenge was handling wildcard characters in the cd command, which could match multiple directories, the current directory, or the parent. This round tested how well I could design clean class structures, handle edge cases, and keep the system extensible.
Phase 3 – System Design and Architecture
This was the most senior-level round. The task was to design the browsing system for an e-commerce platform that highlights trending products using event-based processing.
We discussed how user actions generate events, how Kafka would be used to ingest those events, and how MongoDB would store the product catalog. Redis was used for maintaining fast leaderboards and caching. The interviewer also pushed hard on trade-offs between consistency and availability, based on how real-time the trending system needed to be.
I was even asked to draw out the MongoDB schema to show how product and event data would be structured.
This round felt less like an interview and more like a real engineering design discussion.
What I Learned from Uber’s Interview Process
One of the biggest lessons was that Uber does not want problem solvers who only know algorithms. They want engineers who can combine DSA, low-level design, and high-level architecture into one coherent way of thinking.
Another big takeaway was that explaining your thought process is just as important as reaching the final answer. Silence hurts you more than a small mistake.
Common Mistakes to Avoid
Many candidates fail because they jump straight into coding without explaining their approach. Others know DSA but struggle with system design. Uber expects balance. Weakness in any one area can cost you the offer.
How You Should Prepare for Uber
If you are aiming for Uber, focus equally on three things: advanced DSA, clean object-oriented design, and scalable system architecture. Practice problems that force you to think about performance and trade-offs. Build small systems, not just functions.
Final Thoughts
Getting a 70+ LPA role at Uber is not about luck. It is about mastering the full spectrum of software engineering. If you prepare with depth and clarity, you can absolutely compete at this level.
