How Can HR Verify If an Employee's Past Experience Is Genuine?

I am working in the HR team and I need to know what are the ways to find whether the employee has given fake experience when joining the company. Can it be identified using the candidate's:

1. Pan card
2. Form 16A
3. Whether the Form 16A of the old employer and the new company the candidate joins will clash when filing returns?
4. Can an individual's tax payment details throughout their career be accessed by anyone from the IT office? If yes, what is the procedure and who should we contact to do so?

In HR, it is crucial to verify the authenticity of the information provided by candidates. These methods can help ensure the accuracy of the employee's background and experience.

You could hire an antecedent verification agency to check the credentials and previous salary details of prospective employees. Additionally, you could verify with their previous employer directly after obtaining the prospective employee's consent to do so.

Facilities for providing details from the IT department are currently not available.
