You will not get an instantaneous interview call due to lack of recency, but with previous NB and mil experience you should get called once you fly a bit. 200 hours? 2 years at a regional? Hard to say, but you probably need some kerosene time.

You might be able to fly part time locally, 91/135 stuff, and get a call. Or they might want you to show serious interest by doing penance at a regional (which isn't as bad as it used to be). I'd probably try the former first, unless you're in a big hurry to GTFO your desk job, in which case a regional will be the most predictable and likely fastest route.

I assume you have some TPIC from the mil.

Also understand that getting a major job today can be a full-time job in and of itself, they want you to attend job fairs and maybe jump through some other hoops. Also depends on how high you set the bar... Legacy vs. ULCC.
