Hi Mr. Dundu,
Its a Common Problem to all the HR's, especially to identify the fake experience in IT Industry.
Best thing is to do a back ground check, employee verification with the concerned company, Check out with the website of the company its logo. tally the same with the certificates enclosed.
Also need to know the concerned supervisor of the associate, team size of the respective dept, in the Interview, brief abt the company.
This is what is generally done.
But itseems there are lot of companies established specially to serve the purpose of giving fake experience they do have all the amenities required for any company interms of websites & other registrations.
