🚀 My Uber Frontend Interview Experience | 65 LPA | Software Engineer II
Overview
This document details a frontend interview experience at Uber for a Software Engineer II role. The interview process was structured to assess the candidate's technical abilities, problem-solving skills, and collaborative attributes. The rounds included online assessments, machine coding, specialized depth interviews, collaboration assessments, and data structures and algorithms challenges.
Interview Rounds
Round 1: Online Screening Test (CodeSignal)
The initial screening involved an online assessment on the CodeSignal platform. This round tested the candidate's knowledge of fundamental frontend concepts and problem-solving abilities.
Tip: Candidates should practice competitive programming problems and review frontend MCQs related to browser internals, JavaScript quirks, and debugging techniques.
Round 2: Machine Coding Interview
This round consisted of two parts:
- Project Discussion: The interviewer engaged in a detailed discussion about the candidate's previous project experiences, focusing on implemented performance optimizations and addressed real-world challenges.
- Machine Coding Problem: Grid Light Box: The candidate was tasked with a machine coding problem involving a grid light box.
JavaScript Note: It is recommended to debounce user interactions, particularly when using key listeners for building lightboxes.
Round 3: Depth in Specialization Interview
This round centered on problem-solving and optimization skills. The candidate was presented with the following task:
Task: Memoize an Asynchronous Function
async function getUserData(q, key, cb) {
fetch(`localhost:3000/get/users?query=${q}&key=${key}`)
.then(res => HTTPResponse(res, cb));
}
let memoFun = memoizeUserData(getUserData);
memoFun('test', 100, callback);
Consider using a Map as a cache and a serialize function to generate consistent cache keys for unordered JSON payloads.
Round 4: Collaboration & Leadership Interview
This round assessed the candidate's collaboration and leadership skills. Candidates are encouraged to use the STAR format (Situation, Task, Action, Result) when answering questions and to demonstrate empathy, initiative, and ownership in their responses.
Round 5: Data Structures & Algorithms (DSA)
