I started asking 'what's on-call like?' in first screens. It filtered out two jobs

Didn't think it was a big deal until a recruiter went quiet. One company gave a vague answer, and then I learned one person covers every night page for a whole week at a time. Another said they don't page after 6pm and showed me their incident log to prove it. I ask in the first screen now. It's saved me from at least two bad fits.
