My company has declared bankruptcy and got closed. my salary in this company was very high as i was holding a top management position (Chief Technology Officer). Now, I have passed all technical interviews and tests for another company for the position of Technical Manager. and i will have the final HR interview to discuss the financial issues in the next few days. I know that the pay-scale for Technical Manager is something around 60% of my last salary (and this is what the new companies ready to pay already as i know), and i am fine with this.

Now the question is,
1- from HR perspective, shall i tell them about my last salary (if they asked about it)?
2- do you think it would affect my hiring there if i was getting higher salary in m previous work?

My previous employer declared bankruptcy and was closed. My salary in this company was very high as I was holding a top management position (Chief Technology Officer). 

I have passed all technical interviews and tests with another company for the position of Technical Manager, and I will have the final HR interview to discuss the financial issues in the next few days. I know that the pay-scale for the Technical Manager position is something around 60% of my last salary and I am fine with this.

My questions:

1. From an HR perspective, shall I tell them about my last salary (if they ask about it)?
2. Do you think it would affect my chances for hiring if I was getting a higher salary in my previous work?
