Implement a React CRUD Table | SoFi Interview Question

Quick Overview

The question evaluates proficiency in React front-end development, including component and state design, CRUD interactions with REST APIs, form validation, optimistic updates and rollback handling, accessibility (ARIA/keyboard semantics), and performance techniques such as virtualization and memoization.

React CRUD Data Table — Build and Explain

Context

Design and implement a React application that renders a data table with full CRUD capabilities and a production-ready user experience. Assume a REST API is available; if not, stub/mock one. Optimize for clarity, accessibility, and performance.

Requirements

Data table features
- Pagination (client or server-driven)
- Sorting (single-column minimum; multi-column optional)
- Inline editing (per-row)
- Create, Read, Update, Delete (CRUD)
- Form validation (client-side; surface server-side errors)
- Optimistic updates with rollback on error
- Robust error handling (toasts/banners, retry)
Architecture explanation
- State management strategy (local vs. global/server-state)
- Component structure and responsibilities
- Accessibility considerations (semantics, keyboard, ARIA)
- Performance considerations (virtualization, memoization)

Assumptions (you may adjust as needed)

REST endpoints:
- GET /users?page=1&pageSize=20&sortBy=name&sortDir=asc
- POST /users
- PUT /users/:id
- DELETE /users/:id
Entity fields: id, name, email, role, status

Deliverables

A working implementation or detailed blueprint with code sketches
Explanation of design choices for state, components, a11y, and performance
Notes on pitfalls, edge cases, and validation/rollback guardrails
