In applications
- Copy-paste answers that ignore your screening question or could fit any job.
- A CV that does not add up: overlapping full-time roles, titles that do not match the duties, dates that change between the CV and the profile.
- Tools listed without detail: a long list of software with no example of using any of it.
- No specific achievements: only adjectives such as “detail-oriented” and “hard-working”.
None of these alone disqualifies someone; they tell you what to probe in the interview.
In interviews
- Avoiding video at every stage, or a camera that fails only when you ask a hard question.
- A different person: the voice or face on the call does not match earlier calls or recordings.
- Reading answers: long pauses, eyes moving across the screen, polished answers that fall apart at the first follow-up.
- Cannot explain their own CV: vague about what they did in a role they listed.
- Big gaps between written and spoken English that they cannot explain.
Two follow-up questions on any example (“what happened next?”, “what would you do differently?”) separate real experience from rehearsed stories. Our guide on testing English level shows how to include a live writing task.
In test tasks
- Answers that are polished but generic, with details that do not match your brief.
- Work that the candidate cannot explain on a follow-up call.
- Missed deadlines without a message.
- Asking you for real client data or access to complete a test.
A paid, realistic test with a short follow-up call surfaces most of these; see our test task guide.
In references
- No referee who actually managed the candidate's work.
- Referees with personal email addresses who cannot be found at the company they name.
- Answers that stay vague after follow-up questions.
- Details that contradict the CV.
Our reference check guide shows how to verify referees without sounding suspicious.
Around availability and payment
- Unclear hours: vague answers about availability during your core hours, or a schedule that keeps shifting before the start. It can mean another full-time job.
- Payment to someone else: a request to pay a different person's account or a company that has nothing to do with the candidate.
- Location that does not match: the country they state does not match their documents or payment details. Payment services check this too, and it matters for compliance; we do not recruit in Russia or Belarus.
- Pressure: pushing for an immediate decision, a large advance or unusual payment methods.
Ask directly and kindly. There is often an innocent explanation, such as a recent move; a candidate who cannot give one is the warning sign.
How to respond to a red flag
A single warning sign is a question, not a verdict. Handle it in three steps:
- Name it neutrally: “The dates on your CV and your profile differ; can you walk me through them?”
- Check it with a second source: another short call with a live task, a reference, or the documents you will need for the contract anyway.
- Decide on the pattern: one explained inconsistency is normal; several unexplained ones are a reason to stop.
Write down what you saw and what the candidate said. It keeps the decision fair and consistent across candidates.
Red flags in your own process
Strong candidates usually have options, and they drop out of processes that look careless or risky:
- No pay range in the ad, or a range that changes at the offer.
- Long unpaid tests or “trial days” on real work.
- Weeks of silence between steps.
- A vague role that changes from call to call.
- No written offer or contract.
- Asking candidates to pay for anything, ever.
A clear, quick and paid process is the best filter you have: it keeps the people you want and discourages the rest. Silkstaff's candidates do a written English task and a recorded voice answer when they apply, we check English on a live call before any client interview, and candidates never pay us anything.
Questions
Is it a red flag if a candidate has two part-time clients?
Not by itself; many remote professionals do. It matters whether they can commit to your hours and workload. Ask directly and write the hours into the agreement.
What should I do if I suspect someone else attended the interview?
Ask for another short video call and a live task, and compare. If the doubt stays, do not continue; a hire built on a false identity will not work.
Are candidates who use AI tools a red flag?
Not if they use them openly and can explain and stand behind the result. It becomes a problem when the work does not match the brief and the candidate cannot explain it.
