How an Online Assessment (OA) Works
- You receive a timed link (often 60-90 minutes)
- You solve 1-4 coding problems auto-graded against test cases
- Some OAs include multiple-choice or debugging sections
- A passing score advances you to interviews
Examples
Common examples you will encounter:
- Two LeetCode-style problems in 90 minutes
- A debugging section on a proctored platform
- Multiple-choice CS fundamentals
- A timed HackerRank test
How to Prepare and Succeed
- Practice on the actual platform beforehand
- Read all problems first and start with the easiest
- Handle edge cases — hidden test cases decide your score
- Watch the clock and submit partial solutions
