Jack & Jill is a London hiring marketplace with two AI agents: Jack works for job seekers and Jill for companies. Your first step is a conversation with Jack, by voice call or chat, about your experience, what you want next and what matters to you, which it uses to match you with roles and introduce you to companies that want to meet you. It is free for candidates. This page explains what Jack & Jill is, what the interview is like, what it scores, the rules and practicalities, and how to prepare. We researched Jack & Jill's own candidate pages and independent reports on November 12, 2026; Jack & Jill changes its product often, so check its own pages for the current details.
What Jack & Jill is
Jack & Jill is run by Tinker Tailor Talent Ltd from Shoreditch in London, with an office in San Francisco. Co-founder and chief executive Matthew Wilson previously co-founded Omnipresent, and co-founder Saaras Mehan is chief technology officer. TechCrunch reported a $20 million seed round led by Creandum in October 2025, and the company announced a $40 million Series A led by Air Street Capital in September 2026. It serves the UK and the US. Unlike most AI interviews, this one is not an employer's screening round: Jack builds your profile, a fit score and rankings for matching, and companies decide whether to meet you and then interview you themselves. Jack also runs free mock interviews for specific roles, including coding interviews for engineers.
Who uses it: Corgi, Ramp, Multiverse, Maze and Attio, among hiring companies Jack & Jill names.
What the interview is like
| What to expect | |
|---|---|
| How you start | Sign up on the web with your LinkedIn profile or CV, then talk to Jack; you can also call Jack from your dashboard, or use chat or email |
| Format | A voice call or a text chat with Jack, a voice agent |
| Length | About 20 minutes in Jack & Jill's job-seeker terms and press coverage; its FAQ says about 10, and one Trustpilot reviewer described about 15 |
| What Jack asks | Your experience, what you are looking for and what matters to you in your next role |
| If you skip it | You still get matches, but the terms warn they may be less relevant |
| After | Roles appear within about ten minutes; introductions happen only when a company wants to meet you too |
What it scores
- A fit score, rankings and a profile summary for matching; Jack & Jill's privacy policy describes automated decision-making for matchmaking with regular bias audits, and the site says it is assured by Warden AI.
- Your yes or no on each match, which Jack uses to adjust what it shows you.
- Recordings and transcripts are never shared with prospective employers, the privacy policy says, and contact details are shared only after both sides agree.
- In mock interviews, Jack gives feedback on your stories, your clarity and your answers to the hard questions.
Rules and practicalities
- Calls are recorded and transcribed. Jack & Jill says it creates no biometric voiceprints and does not sell or license your data to train other companies' models; anonymized transcripts may be used to improve its own AI.
- You must be 18 or older, hold one account and give no false information, under the job-seeker terms; inflating your experience only produces introductions you cannot follow through.
- Visibility settings let you choose Open to matches, Exceptional only or Hidden, and you can delete your account in settings.
- Human review is available on request, according to the privacy policy.
- No time limits or retake rules are published; the conversation is ongoing, and you can upload a new CV in settings and keep talking to Jack.
- If an introduction leads to a job, the terms ask you to tell Jack & Jill within 30 days of signing.
From conversation to company interview
- Jack shows roles that fit your profile, usually within minutes.
- You give a yes or no on each match, and Jack adjusts.
- A company that likes your profile requests an introduction.
- Jack contacts you by email or WhatsApp to ask whether you want it.
- If you agree, Jill sends an introduction email to both sides.
- The company runs its own interview process; Jack & Jill says interviews are not guaranteed.
Jack & Jill says most introductions complete within a few days. On Trustpilot it averaged 3.8 out of 5 from 228 reviews when we checked: people praise the natural conversation, the mock interviews and direct introductions, and complain about stale or mismatched roles, roles in countries they cannot work in, and many matches but few interviews.
How to prepare
- Update your LinkedIn profile or CV first; Jack starts from it.
- Decide before the call: target roles, seniority, locations or remote work, salary range and deal-breakers.
- Prepare a two-minute version of your background with the scope of your work, the tools you use and one or two results with numbers.
- Be specific about what you do not want; vague preferences are a common reason for poor matches in reviews.
- Use Jack's mock interview for any company you are introduced to, then rehearse the answers that felt weakest.
Answering well when an AI is asking
- Find a quiet spot with a strong signal and avoid speakerphone, which causes echo.
- Answer every question fully; a skipped question usually scores as missing.
- Keep answers specific: what you did, when, and the result.
- Speak at a steady pace and avoid long silences, which some systems flag or treat as the end of an answer.

Your rights and what happens next
Jack & Jill is not the employer: companies make every hiring decision, and an introduction is not an interview offer. If an introduction goes quiet, ask Jack for a status update or reply to the introduction email.
Because Jack & Jill is a UK company, UK data-protection law gives you the right to ask what it holds about you and to request deletion, and its privacy policy offers human review of automated matching decisions on request. Data it keeps for legal reasons is held for up to two years, it says. You can hide your profile at any time if you stop looking.
Where CoPilot Interview fits
Jack's conversation is your own profile interview, not an employer's test, so the best preparation is knowing what you want and having your evidence ready. The interviews that follow with companies are where practice pays off. CoPilot Interview is an AI interview assistant; its free AI mock interview builds questions from your résumé and the job description, reads them aloud and scores each spoken answer out of ten, which suits rehearsing for a company Jack introduces you to. The free plan gives 15 minutes a day of live help in sessions of up to 15 minutes, with AI mock interviews included. In those company interviews, follow your employer's rules; AI-led rounds and assessments forbid outside help, so prepare for them instead.
Disclosure: CoPilot Interview is our product, so weigh what we say about it accordingly.
