Summary
I recently had the opportunity to interview for a Senior Frontend Engineer position at Apollo.io in India. My interview process involved five rounds: live coding, building a React Todo app, debugging a React music player, a frontend system design, and a final hiring manager discussion, culminating in a job offer.
Full Experience
I had a comprehensive interview experience at Apollo.io for the Senior Frontend Engineer role, which involved five distinct rounds.
Round 1: Live Coding
This round, lasting 60 minutes, took place on the Codility platform. I was given three questions: two focused on JavaScript and one on React. While I don't recall the specific problems, I remember them being relatively easy.
Round 2: App Creation
In this 60-minute round, my task was to build a Todo application using React. The primary focus was on effective state management, specifically implementing filters to display 'all', 'completed', and 'pending' tasks.
Round 3: Debugging Interview
This 60-minute session involved debugging a pre-existing React music player application. The interviewer provided a list of bugs, and my goal was to fix as many as possible within the allotted time. I successfully addressed 17 out of 18 bugs before time ran out.
Round 4: System Design
During this 60-minute round, the interviewer presented a Figma design and asked me to articulate how I would build the application. My discussion covered various aspects including the overall architecture, strategies for improving user experience (UX), different rendering choices (Client-Side Rendering (CSR), Server-Side Rendering (SSR), Incremental Static Regeneration (ISG)), and techniques for network and code optimization.
Round 5: Hiring Manager
The final round was a standard discussion with the hiring manager. We talked about my past projects, how I plan my day, and the expectations for the role. They were interested in assessing my cultural fit and my ability to thrive in a remote work setup.
Ultimately, I was extended an offer for the Senior Frontend Engineer position.
Interview Questions (3)
I was asked to build a Todo app in React. The focus was on how to manage the state for this app, specifically supporting filters like 'show all', 'show completed', and 'show pending'.
I was given a music player application on React which had bugs in it. The agenda of the round was to fix the list of bugs which the interviewer shared with me within the round time. I was able to fix 17 out of 18 bugs before running out of time.
The interviewer shared a Figma design with me and asked how we could build the application. I discussed the overall architecture, strategies to enhance the user experience, various rendering choices such as CSR, SSR, and ISG, and approaches for network and code optimization.
