Are MBB firms about to do a hiring freeze as well?

Hi all, I'm wondering how could I handle this interview time conficts:
A company had a HR interview on Tuesday, and we talked about my availability if the hiring manager want to proceed.
B company requested some additional files on Tuesday, and asked about my availability on Wed.
B scheduled a interview Fri 11am-12pm (received and confirmed around 4pm Wed), and A scheduled a interview Fri 11am-2pm upon "my availability talked yesterday" (received around 4:30pm Wed).

I’m hiring - NY, London or Singapore.
Product management role - DM for details.

Hey everyone! I’m reaching out to crowdsource some opinions for a potential situation I may find myself in at work.

I recently started a new job and it’s a contract position, remote full time at 40 hours a week, paid hourly. I’ve been told several times that work is very light. More is supposed to be coming but no one knows when.

I’m worried that I’ll run out of work and feel bored and unproductive. And I’ll feel obligated to not take the full 40 hours and then lose money. What would you do?
