Coding tests at Singapore employers: HackerRank, CodeSignal, Codility and Glider
Singapore employers mostly send coding tests on four platforms: HackerRank (GovTech, IBM, TSMC, Point72, Visa), CodeSignal (Google, Hudson River Trading), Codility (Grab, Deutsche Bank) and Glider (Shopee). Most are two to five problems in 60 to 120 minutes, many with the camera on. Several employers add a reasoning test alongside, which is where general practice helps most.
- HackerRank is the most common platform, followed by CodeSignal and Codility.
- Typical length: 2 to 5 problems in 60 to 120 minutes.
- Proctoring is common: GovTech candidates reported camera on and full screen throughout.
- Some tests pair coding with reasoning: Visa (cognitive tests), PowerX (picture patterns), Shopee (a pattern-recognition test).
- Google's online assessment was reported to have moved to CodeSignal in 2026.
Which coding platform does each employer use?
| Platform | Employers candidates reported | What the test looked like |
|---|---|---|
| HackerRank | GovTech, IBM, TSMC, Point72, Visa, ByteDance, UBS, JPMorgan, SGInnovate PowerX | ByteDance frontend: 3 problems around LeetCode medium. PowerX: 5 problems in 90 minutes, proctored. Point72: Python and SQL for data roles |
| CodeSignal | Google, Hudson River Trading, Visa, TikTok | HRT: 4 problems in about 70 minutes, the last much harder |
| Codility | Grab, Deutsche Bank, Foodpanda | Foodpanda frontend: 2 problems after screening |
| Glider | Shopee | Data analyst take-home in SQLite and Python; algorithm tests for engineering |
What makes coding tests hard?
In several tests the last problem was the hardest, so bank the easier ones first. Passing some test cases still counts on most platforms, which makes an early working submission worth more than a perfect late one.
Proctoring can end an attempt as surely as a wrong answer. Camera and full-screen rules ended some attempts early, so check your setup before the timer starts. If you're applying for data roles, don't underestimate the SQL: one candidate called a data-analyst SQL question far too hard for a conversion programme.
The reasoning tests that come with coding tests
Several technology employers screen reasoning as well as code. Visa's traineeship paired HackerRank with cognitive tests, SGInnovate's PowerX started with a picture-pattern aptitude test, Shopee used a 30-question, one-hour pattern-recognition test on one programme, and Temus reported 50 questions in 15 minutes. These are the same question types as numerical, logical and CCAT-style tests, and they improve with timed practice.
