Hi can anyone pls help me to answer this:

1)When usually the background check will be done? Before the company give the offer letter or after?
[Larry] Yes, your employer may perform background check on you before or after offer letter.

2)What if I lie during my application e.g. I put my current salary high
[Larry] You must be able to prove to the employer that you are worth the salary you are asking for.
Yes, the employer is able to request for your pay slip from your previous employment, however it is up to you to decide whether to disclose your previous pay information.

My advise, don't lie.

3)Can future employer check about my current salary/epf record. Or when I joined them, can they track my past epf record?
