you can ask about the salary but make sure it is one of the last questions before the interview ends

I am leaving my current job now because of mad office politics and also got 2 warning letters from HR. Therefore, I am just worried if my future employer do a reference check on me.

What do I do?

Yeah, one of my colleagues say like that. Just be honest but in a positive way.

well looking back, that place really not suited for me la. Anyway, I resigned liao. But my colleague told me, just be honest in your next interview but don't bad mouth your ex-company.

Anyway, they don't have much money that's why
