Online Assessment AI Helper — The 2026 Complete Guide
Online assessments (OAs) are the first gate in most tech hiring pipelines. Companies like Amazon, Google, Meta, and Stripe use OAs to filter candidates before interviews. This guide covers how AI assistants help with OAs and what you need to know about each platform.
What is an Online Assessment (OA)?
An OA is an automated coding test sent to candidates after resume screening. It typically includes:
- 2-3 coding problems (LeetCode medium/hard)
- Time limit (usually 60-90 minutes)
- Multiple-choice questions on system design or CS fundamentals
- Behavioral or situational judgment questions
