Employee Background Checks: When Is the Best Time to Conduct Them for Fairness?

Dear seniors, I am facing a huge confusion regarding employee background checks, and I'm in the process of drafting and presenting a policy on the same. My confusion is about which option is fair and safe for both the employee and the organization:

1) Employee check after she has joined the organization
2) Employee check after she was interviewed and before issuing the LOI

Please advise if anything else can be done here.

Thanks in advance.

Companies generally go for verification after the joining, the reason being that there are many candidates who do not join at the last moment. Therefore, a lot of cost, energy, and time goes to waste.

While getting the joining form filled, you should have the candidate sign a statement declaring that all the information provided by them is correct. If it is found to be incorrect, the company reserves the right to take appropriate action.
