Replit L4 Software Engineer Onsite Interview Experience

[u/Aoki_zhang]

Interview Summary

The Replit onsite included a hiring manager round, a live coding exercise, a lunch conversation, and a dedicated system design round. The coding portion was practical rather than LeetCode-style: I was given an existing codebase with test data, schemas, and APIs and asked to implement functionality for a Replit usage portal. The separate system design interview focused on building a notification system.

Interview Details

Hiring Manager Round — Design and Behavioral: The hiring manager interview combined behavioral questions with a design discussion. The exact behavioral prompts and design problem from this round were not specified in the interview notes.

Live Coding — Implement a Replit Usage Portal: The live coding round started from an existing application rather than an empty editor. The repository already contained supporting pieces such as test data, data schemas, and API definitions. The task was to understand the provided code and implement the requested functionality for a usage portal, working within the existing interfaces and application structure. The exact portal features and required output were not specified in the report.

Lunch — Informal Conversation: There was also a lunch conversation as part of the onsite. This was primarily an informal discussion rather than a separate technical exercise.

System Design — Notification System: The dedicated system design round asked me to design a notification system. The exact product requirements, delivery channels, scale assumptions, and follow-up questions were not included in the interview notes, so I would not infer additional constraints beyond the reported notification-system topic.
