When should I interview?

I have heard you can interview for SkyWest at 2 to 3 months before you have the required hours.

Right now I am just shy of 1,100 hours and been working as a CFI but our weather here hasn't been great so I'm not getting much flight time.

There is a hiring event here in late February but I doubt I will be within 2 to 3 months of ATP minimums by then.

Should I wait a couple of months until I am closer to 1500 hours before I interview or would it be ok to interview with between 1,100 and 1,200 hours?

Any ideas?
