🚀 My Uber Frontend Interview Experience | 85 LPA | Software Engineer II

Overview

Uber, a global technology company, connects users to various services through its platform. Known for its large-scale engineering challenges and focus on user interface performance, Uber seeks frontend engineers proficient in JavaScript, ReactJS, and CSS.

The candidate interviewed for a Software Engineer II (SDE-2) Frontend position at Uber. While the candidate was not successful in securing the role, the interview process provided valuable lessons about the skills and preparation required for similar roles.

Interview Rounds

The interview process consisted of a single round:

Round 1: Machine Coding (ReactJS)

The candidate was tasked with building a Pool Widget component using ReactJS within a 60-minute time limit. The requirements included:

• Real-time progress bars
• Conditional rendering
• Functional buttons (Join Pool, Withdraw, etc.)
• Dynamic styling and visual updates
• Modular and reusable component architecture

The candidate completed approximately 75-80% of the widget. The code exhibited clean structure and good modularity; however, time constraints prevented the completion of all edge cases, and the final result wasn't considered production-ready. The panel appreciated the code quality and logic but sought a more complete implementation.

Key Takeaways

For frontend engineers targeting ReactJS-heavy roles, particularly at product-first companies, the following practices are essential:

• Consistent ReactJS Practice: Regular practice is crucial, even when the current role involves other frameworks.
• Focus Areas:
  • State management (local and global)
  • React Hooks (useEffect, useMemo, useCallback)
  • Conditional rendering patterns
  • Code splitting and performance optimizations
  • Component architecture and reusability
• Mock Assignments: Simulating UI challenges under time constraints helps refine skills.
• UI Polish: Attention to detail, edge cases, and final UI polish are critical for demonstrating production-readiness.

Compensation

The recruiter shared the compensation details for the role, which included a fixed base salary of ₹65 LPA and ₹15-20 LPA worth of stock options over four years.
