Mercer Mettl alternatives start with what you use Mercer Mettl for. Its pages describe an online assessment and proctoring platform: psychometric, aptitude and coding tests, AI and human proctoring, and a live coding interview tool. A team that bought it to run proctored tests at scale needs a different shortlist from one that wants to see how a candidate thinks. A test shows the answer. An interview shows the reasoning behind it.
This page lists five options, Tracy AI Interviewer first, with price where it is public and the case where each is the better pick.
Why do teams look for Mercer Mettl alternatives?
Three reasons, from Mercer Mettl's own pages.
- No public price. Its pricing page offers personalised plans and a quote, with no amount listed.

Tracy AI Interviewer: the interview behind the test
Tracy is a two-way video interview run by an AI interviewer. You describe the role and she drafts the questions from your job description, or you bring your own. She asks follow-ups in the person's own field and waits for the answer, reads the CV when your CV check is on, and can run a coding task inside the same interview, with follow-ups on approach and trade-offs. A Director at a top-tier early-stage VC says "Tracy sometimes brings up exactly those questions I might have forgotten to ask, which has been a pleasant surprise." See how AI interviews work.
After each interview you get a recording of both sides, a timestamped transcript, a written assessment for every question with its reasoning, and integrity signals with their evidence: tab changes, gaze, live face detection, delay before answers, fullscreen exits and external screens. A person decides. She has no seats and no upfront cost, and connects through API and MCP, Slack, WhatsApp and Zapier (Connect).
Where Tracy does not replace Mercer Mettl. She does not run proctored exams or psychometric tests. Her integrity signals are evidence for a person to review, not a proctoring suite.

A follow-up asks the candidate to defend the answer a test would only mark.
HackerEarth: AI technical interviews with ID checks
HackerEarth's OnScreen runs adaptive AI interviews in which the candidate writes real code in a live IDE. It lists government-grade ID verification, behavioural monitoring, native Workday, Greenhouse, Lever and Ashby connectors, and SOC 2 Type II. Plans start at $129 a month for 10 invites. Pick HackerEarth when ID checks, proctoring and native ATS decide.
TestGorilla: skills tests with AI interviews
TestGorilla sells a library of 350+ tests on its Core plan. AI interviews, with dynamic follow-ups and scoring criteria you define, are a Plus feature at 2 credits per candidate; Core is from $215 a month and Plus from $520, billed annually; ATS and API integrations are Plus features. Pick it when you want broad skills tests and an AI interview from one vendor at a listed price.
iMocha and Talview: skills tests and proctoring, priced by quote
iMocha pairs a library of 10,000+ skill tests with an AI interviewer called Tara and AI proctoring with timestamped violation logs. Its pricing page leads to a demo, with no price. Talview sells identity verification, proctoring and an AI interviewer called Ivy to high-stakes hirers, and asks for a quote, typically for 150 to 200 candidates or more. Pick either when proctoring and verification matter as much as the interview.

How to choose among Mercer Mettl alternatives
- Start from what the test does for you. If it proctors a campus drive, keep that and add an interview after it. If it screens technical skills, compare the interview.
- Decide whether you need follow-ups. For roles where a correct answer can hide shallow reasoning, pick a two-way interview: Tracy, HackerEarth, TestGorilla, iMocha or Talview.
- Settle price before features. Tracy, HackerEarth and TestGorilla publish a price. For Mercer Mettl, iMocha and Talview, ask for the unit, the minimum and the first-year total at your volume.
- Check the evidence. Ask each vendor to open one completed result and show how a score ties to what the candidate said.
- Run one role. Pick a role with at least 20 applicants and run two options on it. To start with Tracy, send us the role and we build the plan.
