Looking For A Mettl Alternative? A Practical Comparison for Tech Recruiters
Mettl alternative in one line: If you're a tech recruiter evaluating Mercer Mettl and want a shortlist of platforms to compare it against, the most commonly cited options include HackerEarth, TestGorilla, iMocha, Adaface, Codility, HackerRank, Xobin, and Equip. This article compares HackerEarth and Mettl in depth, lists other alternatives worth considering, and answers the questions most buyers ask before switching.
An effective tech recruitment process helps you attract strong candidates, control hiring costs, and build a defensible interview loop. For technical roles specifically, the assessment platform you pick shapes candidate experience, interview signal, and time-to-hire.
Mercer Mettl and HackerEarth are two of the better-known online technical assessment platforms. Below, we compare them across features, security, pricing, and reviews — and we also cover the broader Mettl-alternative landscape so you can build a real shortlist.

Other Mettl alternatives worth shortlisting
Before diving into the HackerEarth vs. Mettl comparison, here are the alternatives most frequently named in analyst listings and buyer guides (Gartner Peer Insights, Adaface, ProProfs):
- HackerEarth — technical assessments, coding interviews, hackathons; strong for developer hiring.
- TestGorilla — broad test library across cognitive, personality, and role-specific skills; popular for non-technical hiring too.
- iMocha — large skills library with a focus on enterprise skill assessment and upskilling.
- Adaface — conversational assessments; positioned around candidate experience.
- HackerRank — developer skills platform with a large public developer community.
- Codility — engineering assessments and CodeLive interviews.
- Xobin — talent operating system aimed at faster screening.
- Equip — lightweight skill assessments across devices.
- The Predictive Index — talent optimization and behavioral assessments.
- Criteria — pre-employment testing across cognitive, personality, and skills.
If your hiring is primarily non-technical, tools like TestGorilla, Criteria, or The Predictive Index may fit better than a developer-focused platform. If your hiring is small-scale (fewer than ~10 hires a year) or your roles require a very broad assessment catalog outside software engineering, Mettl's wider psychometric and domain library can be a stronger match than a developer-first tool.
HackerEarth
HackerEarth is based in San Francisco and offers enterprise software for technical recruitment. Its products include coding assessments, remote video interviews, and hackathons. It's built primarily for teams hiring software engineers and other technical roles at scale.
Mercer Mettl
Mercer Mettl offers a broader range of assessment solutions across industries including IT, banking, healthcare, and retail. It provides tests for coding, language, cognitive ability, personality, and domain skills, plus tools for L&D and internal mobility. Mettl is an India-headquartered company (part of Mercer, a Marsh McLennan business), which is one of the questions buyers frequently ask.

Where Mettl tends to be the stronger fit
To be even-handed: Mettl has genuine strengths a comparison should acknowledge.
- Breadth of catalog. Mettl's assessment catalog spans psychometric, behavioral, language, and domain tests across many industries — useful if you hire beyond software engineering.
- Established enterprise footprint in India and APAC, with Mercer's backing.
- Proctoring and certification use cases. Mettl is widely used for high-stakes certifications and exams, not only recruitment.
- Non-technical hiring. For sales, operations, or entry-level cognitive screening, Mettl's out-of-the-box test library is deep.
If your primary hiring problem is "assess 50 different non-engineering roles across 5 business units," Mettl's catalog breadth is a real advantage.
Where HackerEarth tends to be the stronger fit
- Engineering-first workflows. Coding assessments, developer-friendly IDEs, and pair-programming interviews are core, not add-ons.
- Hackathons and employer branding. HackerEarth runs company hackathons on the same platform used for hiring assessments.
- Skills coverage. HackerEarth's product catalog lists 1,000+ skills covered across its assessment library.
Features and functionality
Both platforms let you build and administer online tests — MCQs, coding tasks, and role-based assessments — with proctoring and automatic evaluation.
HackerEarth's product surface is oriented toward engineering hiring: coding environments, project-style problems, and integrations with ATSs common in tech. Mettl's product surface is broader and includes psychometric and language batteries that HackerEarth does not focus on.
If a buyer's ask is "we need one platform for tech and non-tech hiring," Mettl covers more ground out of the box. If the ask is "we need deep signal on engineering candidates," HackerEarth is built around that use case.
Test creation and administration
HackerEarth: Recruiters can assemble tests from HackerEarth's library or create custom questions. According to HackerEarth's product catalog, the library covers 1,000+ skills.
Mettl: Mettl offers a wide catalog of ready-made assessments. Buyers evaluating Mettl have reported (see reviews on G2 and Gartner Peer Insights) that some customization requests are handled by Mettl's team rather than fully self-service, which can add turnaround time. Confirm the current self-service scope with Mettl directly, since product capabilities change.

Reporting and analytics
HackerEarth: Provides dashboards and candidate performance reports, including code-related scoring signals in candidate reports. Customization depth varies by plan.
Mettl: Provides reporting dashboards across its assessment types. Depth of customization and the specifics of code-quality analytics differ from HackerEarth's approach; buyers should request a live demo of the report views for the specific roles they hire.
If highly customized reporting is a hard requirement, ask both vendors for sample reports before deciding.

Security and data privacy
Both platforms position themselves as enterprise-ready and reference GDPR compliance in their marketing.
Rather than take either vendor's word for it, ask for:
- Current SOC 2 or ISO 27001 audit reports.
- A written statement of GDPR data-processing role (controller vs. processor).
- Details on data residency, encryption in transit and at rest, and access controls.
- Proctoring specifics: IP restrictions, MFA for admin accounts, browser lockdown behavior.
For background on GDPR obligations for HR data, see the European Data Protection Board and the official GDPR text. For CCPA, see the California Attorney General's CCPA page.
We recommend confirming any specific security claim — from either vendor — with a current compliance document rather than relying on a marketing page.
Pricing
Neither HackerEarth nor Mettl publishes pricing publicly. Both operate on custom quotes tied to hiring volume, features, and contract length.
If you're searching for "Mettl alternative free," note that most enterprise assessment platforms in this category — including HackerEarth, Mettl, TestGorilla, and iMocha — do not offer a permanent free tier for recruitment use. Free trials or demos are common; a permanent free plan is not. Tools like Equip and some ProProfs plans have lower entry price points if budget is the primary constraint.
When comparing quotes, ask each vendor for:
- Price per assessment, per candidate, or per seat.
- Overage charges beyond contracted volume.
- Cost of proctoring, live interviews, and integrations.
- Contract length and renewal terms.
User experience
HackerEarth's interface is oriented toward recruiters running technical assessments and candidates taking coding tests, with an in-browser IDE. Mettl's interface spans a wider range of assessment types, which some reviewers describe as more complex to learn but broader in what it supports (see G2 reviews).
Candidate experience is worth testing directly: run yourself and a peer through each platform's candidate flow before signing.

User reviews and feedback
Both platforms carry ratings in a similar range on G2 (around 4.4 / 5 at time of writing — verify current numbers). HackerEarth reviews frequently mention customer support responsiveness and the coding assessment experience. Mettl reviews highlight catalog breadth and note a steeper learning curve for administrators new to the platform.

Frequently asked questions
Is Mettl an Indian company?
Mercer Mettl was founded in Gurugram, India, in 2010 and was acquired by Mercer (part of Marsh McLennan) in 2018. It operates globally today but its product engineering and a significant part of its operations remain based in India.
Is there a free Mercer Mettl mock test available?
Mettl offers sample assessments and free mock tests for certain skill areas via its website, and candidates preparing for Mettl-administered exams can often find practice tests through third-party prep sites. There is no permanent free tier for employers using Mettl for recruitment; access for hiring teams is via paid plans or a requested demo. Check mettl.com for current availability.
Is the Mettl test proctored?
Yes. Mettl offers proctoring on its assessments, including AI-based auto-proctoring, live human proctoring, and record-and-review options. The specific proctoring level depends on the plan and the test configuration selected by the employer.
Is Mettl safe?
Mettl states that it follows enterprise security practices and references GDPR compliance. For a definitive answer, request current audit documentation (SOC 2, ISO 27001) and a data-processing agreement from Mettl directly. Third-party enterprise buyers typically validate this through their infosec review rather than relying on marketing claims.
What is the best free Mettl alternative?
There is no like-for-like free replacement for Mettl at enterprise scale. For small teams or occasional use, Equip and some ProProfs plans have low-cost entry points. For a free trial before committing, most vendors — HackerEarth, TestGorilla, iMocha, Adaface — offer demos or limited trials on request.
How does TestGorilla compare to Mettl?
TestGorilla is often shortlisted alongside Mettl for teams that hire across both technical and non-technical roles. TestGorilla's library leans toward role-based and cognitive tests; Mettl's library is broader on psychometrics and certifications. For pure engineering hiring, developer-focused tools (HackerEarth, HackerRank, Codility) tend to give sharper signal than either.
Choosing between them
Both HackerEarth and Mettl are credible platforms with real strengths. The right choice depends on what you hire for:
- Mostly software engineers, at volume, with hackathons or campus hiring in the mix → HackerEarth is built for this workflow. See our assessments product page or the HackerEarth vs. Mettl comparison for role-by-role detail.
- Cross-functional hiring, non-technical roles, or certification use cases → Mettl's catalog breadth is a genuine advantage.
- Small teams, fewer than ~10 hires a year → A lower-cost tool like Equip or a TestGorilla starter plan may fit better than either.
If you'd like to see how HackerEarth handles a specific role you hire for, request a demo and ask the team to walk you through the assessment and reporting for that exact role — not a generic tour.
