HackerRank
Technical screening and interviewing platform for engineering hiring, with a coding environment, plagiarism controls and a tiered question library. Sold per attempt, from $79/month billed annually.
TestGorilla
Pre-employment assessment platform with a library of 350+ tests, video questions and AI interviews, charged in credits per candidate rather than per seat.
HackerRank vs TestGorilla
HackerRank charges per attempt for engineering-specific coding work in the same environment the live interview runs in; TestGorilla charges per candidate across a broad skills library and gives the top of the funnel away for nothing.
Quick verdict
ClearThe evidence points firmly at one of the two for the situations below.
Choose HackerRank if
- You are hiring engineers and the screen has to be real code, with the live interview happening in the same environment rather than in a shared document
- Advanced plagiarism detection and leaked-question protection have to be there from the entry plan, because the answers to standard questions are a search away
- You hire in bursts and want the annual attempts pooled across the year rather than buying for your busiest month twelve times
Choose TestGorilla if
- You test roles outside engineering and need a library that covers them, where the vendor states 350+ tests across skills
- You want a free tier that renews rather than expires: EUR 0 a month with 10 credits every month and one full-access seat
- You want the top of the funnel to cost nothing — resume scoring, qualifying questions and custom questions consume no credits on any plan
Neither, if
- You hire a handful of people a year: the free tier on one side or nothing at all is the honest answer, and a single-user entry plan is not a purchase worth managing
- You need assessment results inside your ATS without paying to upgrade, because both put that behind a higher plan
- You need published evidence that the tests predict performance or do not create adverse impact — neither vendor establishes that here
Summary
Choosing how candidates are tested before anyone spends interview time on them
What they have in common
Both publish their prices, which is unusual in this category. Both put ATS integration behind an upgrade rather than on the entry plan, both bill annually on the paid tiers, and neither has published evidence that its tests predict on-the-job performance.
Where they really differ
Who you are hiring. One library is built for developers and the product is built around running a coding exercise and a live pair-programming session on the same tooling; the other is built for testing skills across roles, with resume scoring and qualifying questions in front of it.
Who this decision is for
A team deciding whether its screening problem is engineering-shaped. If every role you test is a developer role the answer is usually already decided; if half of them are not, the library is the constraint.
Decision guidance
Choose HackerRank if you are primarily hiring engineers and developers and need deep technical coding assessments. Choose TestGorilla if you hire across many different roles and need a versatile assessment platform covering cognitive, personality, and role-specific skills tests.
Summary
HackerRank and TestGorilla both offer pre-employment assessments but with very different focuses. HackerRank specializes in technical coding assessments with AI-powered challenges, plagiarism detection, and deep engineering evaluation. TestGorilla offers a broader assessment platform with 400+ science-based tests covering cognitive ability, personality, culture fit, and role-specific skills beyond just coding. HackerRank is the go-to for engineering roles, while TestGorilla covers a much wider range of positions and assessment types.
Side by side, on what decides it
The deciding criterion here is: Whether the roles you are testing are engineering roles, because each library was built to answer a different question
| Decision factor | HackerRank | TestGorilla |
|---|---|---|
| The unit you are charged in | Attempts, at USD 20 for anything beyond the plan | Credits per candidate: 1 for a skills test or video question, 2 for an AI interview or job simulation |
| What the entry plan costs and carries | USD 79 per month billed annually: one user and 60 attempts for the year | EUR 0 per month with 10 credits monthly and one full-access seat; Core is EUR 66 per month |
| Where ATS integration begins | Pro, at USD 419 per month, which is also where unlimited users starts | Plus, from EUR 345 per month with an annual commitment starting at EUR 4,140 |
| What the library is built for | Developers: 2000+ questions on Starter, 4000+ on Pro, 7500+ on Enterprise | Skills across roles: 350+ tests, vendor-stated, plus video questions and job simulations |
| What costs nothing | Not established: the plan allowance is the attempt budget | Resume scoring, qualifying questions and custom questions, on every plan; credits are charged only once a candidate starts |
| Whether the offer changes by region | Not established in HackerRank's brief | Core reads EUR 66 a month for 250 credits a year in Europe and USD 142 a month for 400 credits in the United States |

Where HackerRank wins
The take-home and the live session share one environment
Screen and Interview are both included from the entry plan, so the exercise a candidate does alone and the pair-programming session that follows run on the same tooling. The alternative most teams fall back on is a shared document and good intentions.
Integrity controls are not an upsell
Advanced plagiarism detection and leaked-question protection are included from the entry tier. In a market where the answer to almost any standard coding question is one search away, putting that behind a higher plan would make the entry plan close to decorative.
Seasonal hiring does not have to buy for its peak
Annual plans pool attempts across the year, so a team that hires forty engineers in one quarter and none in the next is not paying twelve times for its busiest month. Extra attempts beyond the plan are a stated price rather than a renegotiation.
Where TestGorilla wins
A free tier that renews instead of counting down
EUR 0 a month with ten credits every month, essential skills tests and one full-access seat, renewing rather than expiring. A small team can screen continuously without a contract, which no trial period allows and which is a genuinely different offer from a countdown.
The candidates who fail the first filter cost nothing
Resume scoring, qualifying questions and custom questions consume no credits on any plan, and a credit is only spent once a candidate actually starts the assessment. For a high-applicant funnel that means the expensive step happens after the cheap filter has already run.
Adding a colleague does not add to the bill
Costs follow candidates rather than seats, so a hiring manager who wants to review results is not a licensing decision. On the other side the entry plan carries a single user, which makes the second reviewer an upgrade rather than an invitation.
Trade-offs that apply either way
The entry plan is not where the product actually lives
On both sides the useful configuration — results inside your ATS, more than one reviewer, the full library — sits on a higher tier, and the step up is large in both cases. Price the plan you will be on in month six, not the one you will sign in month one.
Whether the tests actually predict anything is unestablished
Neither brief records evidence on assessment validity, and one explicitly records adverse impact as unknown. Both products will happily filter your funnel; whether the people they filter out would have done the job is a question neither vendor answers here.
The advertised price is the annual price
Both headline figures assume a commitment: one is billed annually with the monthly route costing more and allowing less, the other has no month-to-month option on either paid plan. A seasonal peak has to be paid for across the whole year on both sides.
Reading the two price models
- Both publish, so this is one of the few comparisons in the catalogue where the arithmetic can actually be done — but only after converting to the same unit, because attempts and credits are not the same thing.
- On the credit side an AI interview or job simulation costs 2 credits rather than 1, so a 250-credit year is 125 candidates if that is your format. Halve the allowance before comparing it to an attempt count.
- Prices and allowances quoted by American review sites will not match a European invoice on the TestGorilla side: the same Core plan reads EUR 66 a month for 250 credits a year in Europe and USD 142 a month for 400 credits in the United States.
Best by scenario
A company hiring 30 backend engineers this year
Every role tested is a developer role, the screen has to be real code, and running the live interview in the same environment removes a handover the other side does not cover.
A support and operations team screening 400 applicants a quarter
The roles are not engineering roles, the funnel is wide, and the free top of the funnel means the credit budget is only spent on candidates who cleared the qualifying questions.
A ten-person startup making four hires this year
Ten credits a month covers four hires without a contract. Paying for either paid plan at that volume buys process a team of ten does not yet need.
What this comparison does not know
Unknowns stay unknown. Verify these with the vendor before deciding — they are the gaps that would change the answer.
