Codility vs HackerRank: which technical assessment fits your engineering hiring?
Codility and HackerRank are two of the most-used technical assessment platforms for engineering hiring. Both run async coding tests, both have live IDE interview tools, and both score in the 4.6/5 range on G2. Codility leans into engineering skills mapping for existing employees. HackerRank leans into a larger test library and a developer audience that already knows the brand. Here is how they compare.
Codility is a technical assessment platform for enterprises hiring and developing engineering talent. It does the hiring assessment piece (coding tests, live interviews) and adds an internal piece (skills mapping for existing employees).
Key capabilities:
Asynchronous coding screening assessments
Structured live technical interviews
Engineering skills mapping for employees
Role-specific task library and templates
Plagiarism detection and proctoring controls
Custom assessment creation with Task Builder
AI assistant for assessment workflows
G2 rating: 4.6/5 across 865 reviews.
What HackerRank does
HackerRank is a technical hiring platform with one of the largest test libraries in the category. The brand is well-known among developers, which is both a feature and a friction point (some candidates refuse to take HackerRank tests).
Key capabilities:
Role-based coding assessments and a large test library
Live technical interviews in a shared IDE
AI-powered plagiarism detection
Certified assessments for standardized screening
Real-world coding questions and tasks
ATS integrations and structured scorecards
G2 rating: 4.6/5 across 545 reviews.
Where they differ
Codility includes employee skills mapping. HackerRank does not. If you want one tool that handles both hiring assessments and internal engineering skill assessment, Codility is the broader pick. HackerRank stays focused on hiring and pairs that with a deeper hiring-test library and a more mainstream developer audience.
Codility strengths and weaknesses
Strengths:
Realistic coding challenges and live interview environment.
Efficiency gains in screening large candidate volumes.
Standardized evaluations help reduce bias.
Broad assessment plus interview capabilities support remote hiring.
Weaknesses:
Timed coding tests can feel artificial and stressful.
Reviewers note the platform lacks a debugging pane for unit testing before submission.
Assessment quality depends on test setup and calibration.
HackerRank strengths and weaknesses
Strengths:
Large test library covers most engineering role types.
Live coding interview environment supports remote technical screening.
Improves hiring accuracy and reduces screening time per reviews.
Weaknesses:
Some users report a lack of clarity when creating tests.
Many top candidates refuse to take HackerRank tests (brand fatigue).
Question styles may not always reflect real-world senior engineering work.

Key differentiator
Codility and HackerRank both measure coding skill. The difference between them is breadth (Codility extends to employee skills mapping; HackerRank stays in hiring). Neither measures personality, situational judgment, or environment fit. For non-coding signal, you need a different tool.
Codility vs HackerRank: pricing
Codility pricing: $1,200 flat-rate (annual) per their public pricing page. Higher tiers and enterprise plans are quote-based.
HackerRank pricing: starts at $165/month flat-rate with a free trial. Higher tiers and certified assessments are quote-based.
Truffle pricing: $149/month, or $99/month billed annually. No contracts, no per-seat pricing. 7-day free trial, no credit card.
What you get for the price
HackerRank Starter ($165/mo or $1,980/yr) and Codility entry ($1,200/yr) cover coding tests for technical hiring at small scale. The pricing is in the same range.
Truffle is a different shape: $149/month covers resume screening, one-way video interviews, three assessment types, and unlimited positions. Pick the tool that matches your hiring problem (coding tests vs broader candidate signal), not just the price.
Verdict
Codility and HackerRank are both legitimate picks. They are similar enough that the right answer often comes down to one or two specific needs.
Pick Codility if you want technical assessment plus employee skills mapping in the same tool. Codility's enterprise positioning suits global engineering organizations.
Pick HackerRank if you want a deeper hiring test library, a more mainstream developer audience, and a published starting price ($165/mo) with a free trial.
Neither tool answers questions outside coding skill. Most hiring decisions for non-engineering roles, and many decisions even for engineering roles, depend on signal that coding tests do not capture. Truffle's assessments measure personality, situational judgment, and environment fit, and pair with one-way video interviews and resume scoring in one workflow.
Why teams pick Truffle
Codility and HackerRank measure if a candidate can code. Truffle measures whether a candidate is the right hire. Different questions, different tools.
What Truffle does that coding tests do not:
Validated personality assessments. IPIP Big Five inventory, scientifically validated, scored against the trait profile your team has decided fits the role.
Situational Judgment Tests. Real-world dilemmas scored against your team's preferred approach. Different from "is this answer right" — closer to "is this how we work."
Environment Fit assessments. Surface whether a candidate's work-style preferences (remote vs office, deep work vs interrupt-driven, autonomy vs structure) match the actual role.
One-way video interviews. Candidates record on any device. Truffle's AI generates a transcript, an AI Match score, an AI Summary, and a 30-second Candidate Shorts highlight reel.
Resume screening. Rubric-based scoring with reasoning attached, so you can audit it.
If your only constraint is "can this candidate write Python," Codility or HackerRank is the right pick. If your constraint is "can this candidate actually do the job and stay," Truffle gives you signal coding tests miss.
$149/month. $99/month annual. 7-day free trial, no credit card.
Is Codility or HackerRank better for technical hiring in 2026?
Both have nearly identical G2 ratings (4.6/5) and similar core capabilities. Codility includes employee skills mapping. HackerRank has a larger hiring test library and a more mainstream developer brand. The right pick depends on whether you want hiring-only (HackerRank) or hiring plus internal skill assessment (Codility).
How much does Codility cost compared to HackerRank?
Codility starts at $1,200 annual (per their public pricing page). HackerRank starts at $165/month flat-rate ($1,980/year), with a free trial. The annual entry-level cost is in the same range. Higher tiers at both vendors are quote-based.
Should I use Codility or HackerRank for non-engineering roles?
Neither. Both are technical assessment tools. Neither measures personality, situational judgment, or environment fit. For sales, ops, support, hourly, or other non-engineering roles, use a screening platform that runs validated personality and situational assessments. Truffle is one option that does this and includes one-way video interviews and resume scoring in the same workflow.
Are Codility and HackerRank tests AI-resistant in 2026?
Both have plagiarism detection and proctoring controls. Both detect copy-paste and screen anomalies. Neither is fully AI-resistant: a candidate using a separate device with ChatGPT can still solve many test types. Truffle's assessments (Personality, SJT, Environment Fit) are designed AI-resistant by default — they measure traits AI cannot fake.
What are the G2 ratings for Codility and HackerRank?
Codility has a G2 rating of 4.6/5 across 865 reviews. HackerRank has a G2 rating of 4.6/5 across 545 reviews. Identical ratings. Codility has the larger review count, which slightly increases statistical confidence.
