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?
2)What if I lie during my application e.g. I put my current salary high
3)Can future employer check about my current salary/epf record. Or when I joined them, can they track my past epf record?
4)Can my HR disclose my payslip if future employer contact my current employer?

So how to answer let say the company insist to know my salary? I know the salary should be P&C. I think all company's policy is not to disclose your salary.

1.Not for now. I am enjoying my time with my current company. Just that I have friend of a friend who is HR and she said that for all candidates she will ask them to tell her/manager their current salary during interview/in application form because of the company "standard process". She said it is required to know the market salary and for future hiring. I don't want to ask panjang2 as I am barely know her. That is why I'm wondering what if the candidate don't want to tell HR their salary. Can HR still know about it? Because from my perspective, I think it is not fair to the candidate. Sometimes they just do the interview just to survey the market salary. Very pity to those who put high hope.

2.I think just verbal. Not to that extent.

3.I am just asking. Didn't apply any job for now.
