On online job search platforms, some people may falsify their academic qualifications and work experience to obtain senior positions. Common methods include: 1. **Fake diplomas and certificates:** Making or purchasing fake academic diplomas and certificates to make them look authentic. 2. **Fictitious work history:** Falsifying past work experience, including fabricating non-existent companies or positions, or exaggerating one's responsibilities and achievements in previous positions. 3. **Falsifying letters of recommendation and contact information:** Creating fake letters of recommendation and providing fake contacts or friends as fictitious former colleagues or supervisors. 4. **Modifying resume details:** Falsifying graduation time, major, skills or project experience in resumes to meet job requirements. 5. **Establishing a false online identity:** Establishing a false professional image on social media or professional social networks (such as LinkedIn), posting carefully designed professional dynamics and personal connections. 6. **Using third-party services:** Some unscrupulous companies or individuals provide specialized services to help falsify work experience, diplomas and background check information. 7. **Fabricating project experience:** Fabricating projects that have been involved in, claiming to have played an important role, and providing false project results and colleague evaluations. To identify and prevent these schemes, employers typically conduct rigorous background checks, contact real references and companies, require physical proof during interviews, and verify a candidate’s actual abilities and experience through behavioral interview questions.
