700-800 is realistically competitive. Some get hired with a bit less.

FOs at my base were typically flying about 80hrs/month. WX/MX cancellations would sometimes bring that number down (especially over the winter). FOs who picked up trips at other bases sometimes were doing over 100hrs/month.

FOs definitely log hours (even when the autopilot works), as per company GOM/Op Specs. ASEL, CC, IMC, and night- but very little PIC.
