How do I know a remote candidate is real?

Check their ID against a government document with a liveness step, and make sure the same person appears on every call. Ask detailed follow-ups about their own projects, and contact references through channels you find yourself.

What is a proxy interview?

Someone other than the applicant takes the interview, or feeds them answers in real time. Detailed follow-ups, screen-shared work and an ID check with the same face on every call make it much harder.

What does vetted in advance mean?

Someone checked the candidate before you see them. Ask exactly what was checked: identity, skills, judgement, references. "Vetted" means different things on different platforms.

Are one-way video interviews useful for data roles?

A short video intro shows how someone explains their work, and it helps you confirm identity later. It doesn't replace a live technical conversation.

What is a working-style or behavioural assessment?

A structured set of work scenarios that shows how someone tends to work: autonomy, communication, handling pressure. Use it to shape your interview questions, not to pass or fail people.

How to spot fake candidates and verify remote data hires

Last updated 18 Oct 2026

Remote data engineering roles attract templated CVs, proxy interviewers and AI-coached answers. Before you make an offer, check four things:

they are who they say they are (an ID check, and the same face on every call);
they can explain their own work in detail;
they can handle real data scenarios;
how they actually like to work.

Vetted carbon.talent profiles bring that evidence with the application: a vetting report, a working-style profile and a short video intro. On Team and Scale you can add an ID check.

Warning signs in data applications

Several CVs with near-identical bullet points. Sometimes the industry doesn't match the employer.
Every tool in the stack is listed, but no outcome is specific.
Vague about location, notice period or when a "current contract" ends.
The camera is "broken" on every call, or the person looks different from their photo.
Long pauses, then fluent textbook answers. They can't go deeper on their own project.
They refuse any live or screen-shared work.

A verification checklist, in order

Before the first call. Read for specific outcomes they owned. Pick one CV bullet and ask a written question about it.
Video intro. Ask for a short, unedited video explaining a recent project and one decision they'd change. Fraudulent applicants tend to drop out here, and real ones show how they communicate.
Identity. For finalists, check a government ID with a liveness step. After that, make sure the same person is on every call.
Scenario interview. Use your own anonymised problem and ask "why" three times. Proxies and scripted answers break down on follow-ups. See data engineer interview questions.
Short live practical. Screen-shared, with normal tools allowed. Discuss it as they go.
Working style. A behavioural or work-style profile tells you what to ask about autonomy, communication and handling pressure. Use it to guide the conversation, not to pass or fail people.
References. Reach them through a company channel you find yourself, not only through contact details the candidate gives you.
Before access. Don't give access to production data until every check is complete.

What each check catches

Check	Catches	Doesn't catch
ID check	A fake or borrowed identity	Weak skills
Video intro	A mismatched person, poor communication	Coached answers on their own
Scenario questions	Shallow experience, scripted answers	Identity fraud
Working-style profile	Fit with how your team works	Skills or identity
References	Invented work history	A real person who's a poor fit
