See, it’s not easy to catch them. People are experts in doing this kind of fraud. You won’t believe there are many cases in which the candidate even chooses a proxy candidate or a fake candidate to interview on their behalf since you don’t meet them in person. You will never realize that he is not a candidate who applied for the job. They can even show you fake documents about their identity during the interview. You will not be able to check the authenticity of those documents at the time of the interview.

Steps you can take to stop this

If you are interviewing someone on a skype or any other video conferencing app, you can record the meeting or take the screenshot, of course, with their permission, and later you can compare the photos.

If you are not very well aware of this technology, you can hire someone who does all these jobs on your behalf; for document verification, you can ask them to post you all their credentials and passport size photos.

I work in an IT company, and my company faces this issue frequently, sometimes I have seen by myself then the company spent a lot of resources on them and later found out that the candidate is not the same who gave an interview. To stop this, we hired a professional company, Candidate Identity Verification – CelebratingLife who does all these jobs on behalf of the company; they took various information from the candidate to ensure that the right candidate was involved in the whole process. They used AI for Candidate Verification which makes sure to take proper actions to do the background check of the interviewers.
