How staffing and nearshore firms stop proxy candidates

You vouch for every person you submit. If the person on assignment is not the person the client interviewed, the problem lands on your firm, not only on the candidate. This guide is for owners of remote developer staffing and nearshore firms. It covers where proxy candidates get in, what to check at each stage, and what to do when you suspect it but cannot prove it.

Why this risk lands on staffing firms

A hiring team that gets this wrong loses a hire. A staffing firm also risks the client's trust. The American Staffing Association's tool kit describes the bait and switch as the candidate hired being "not the worker that shows up for the assignment".

It reaches large firms too. The Paypers reported on October 23, 2026 that Kforce, which places about 17,000 consultants a year, saw a rise from 2024 in cases where the person who arrived was not the person the recruiter and client had interviewed. In some cases it learned of this "weeks later, when a client raised concerns".

Your clients are also being told to look at you. In a January 2025 notice the FBI told employers to "Verify third-party staffing firms conduct robust hiring practices and routinely audit those practices". Its July 2025 notice says companies that outsource IT work "are removed from the direct hiring process". Both notices are about North Korean IT workers, but a client that reads them will ask the same questions about any supplier.

of US managers have confirmed a proxy in an interview (Checkr, October 15, 2026)

33%

more strongly suspected one but could not prove it (Checkr, October 15, 2026)

That is a vendor's survey of 3,000 US managers involved in hiring, not of staffing firms. It still shows how often people are left with a doubt and no proof.

What it looks like: proxy interview, bait and switch, lip syncing

The proxy interview guide covers these forms in more depth, and why the signs people notice are not proof.

What to check at each stage

Timing matters. In the same survey, 29% of companies verify identity as soon as someone applies, 49% wait until after at least one live interview, and 18% wait until the final interview or later. For a staffing firm, the safest pattern is a light check at every stage.

1. Intake. Look for the same phone number or email on more than one resume, which the FBI says it has seen. Compare the resume with public profiles, and confirm past employers yourself, not through details on the resume.
2. First screen. Confirm who the person is, with the camera on, and note what you saw so later rounds have something to compare with. Ask for consent before you record anything.
3. Deep resume round. This is the strongest thing an interviewer can do live. BrightHire's guide says a stand-in struggles with "specific follow-up questions about decisions, tradeoffs, and mistakes" from past projects. Build each question on their last answer, for example: what broke after that release, who found it, and what would you change now?
4. Client interview. This is where a swap costs you most. Have someone who met the candidate compare notes afterwards, on appearance, communication style and speech, and check the interview itself.
5. Day one. Confirm the same person before any client system opens to them. The FBI advises: "do not grant access to any systems until the background check is completed". Treat a late change of shipping address or payment details as a reason to ask.

If you suspect it but cannot prove it

Do not accuse anyone, and do not let it pass. Checkr found 28% of managers admit they have knowingly moved a candidate forward despite suspecting dishonesty. For a staffing firm, that doubt then travels to your client.

1. Write down what you saw. Times and specifics, no conclusions. BrightHire's advice is to flag it for review "rather than confronting the candidate mid-call".
2. Remember what signs are. A slow connection, nerves and a cheap camera look the same as many warning signs. Honest candidates deserve a fair next step. To sort out what you noticed, use the free Was that a proxy? check.
3. Add a short second call. Use a different interviewer, camera on, no shared screen, with follow-ups on details from the first call.
4. Repeat the identity check. Make this a standard step for everyone at that stage, so no one is singled out.
5. Hold the submission until you can confirm. If the person is already with the client, say what you checked and what is still open. Say you could not confirm something. Do not state a conclusion you cannot back up.

If a different person showed up after the hire

Move in this order, and bring in your lawyer early. This is general guidance, not legal advice.

1. Protect the client. Limit access while you look into it. When companies find this kind of case, Checkr says 48% terminate the employee, 43% launch an internal investigation and 28% revoke system and data access.
2. Confirm the facts. Compare interview notes, any recordings you have consent for, and changes to address or payment details.
3. Tell the client early. Follow your contract. Say what you know, what you have done and what happens next.
4. Check your supply chain. If a subcontractor or nearshore partner sourced the person, ask for their records, and audit how they vet people.
5. Report it where it applies. The FBI asks companies that find this type of activity to report it to the IC3 at ic3.gov.
6. Write the process down. Checkr found 44% of companies lack a formal, written process for verifying identity after hire. A written one is also something you can show clients.

Are in-person finals the answer?

They work for the round they cover, and they are the costly option. Checkr reports that Google, Cisco and McKinsey have brought back on-site interviews. For a nearshore firm, flying each finalist in works against the reason clients come to you: fast access to remote developers. An in-person round also covers one day, so it does not stop a switch after the offer. Keep it for your highest-risk roles, and use the stages above for the rest.

Where Verified Call fits

Verified Call checks the person on a video call, before and during it, without joining. The host turns it on for guests in Google Calendar. The candidate agrees on a consent screen and runs the Verified Call app, which keeps checking during the call for hidden AI tools, camera software and a change of face. The host sees a badge next to each person: Verified, Needs a look with the proof, or Can't confirm. Every interview starts a fresh check, so a client round gets a full check of its own.
