Had a buddy that got his ATP, interviewed with UAL on Monday and bought 2hrs of sim time the day before the interview. Every other fighter/attack pilot I've talked to about this says you need sim time because you have no idea how to fly a 737. My point is, after spending $3000 on an ATP then another $1100 on sim prep for an interview he could have spent a little more and got an 737 type. Necessary? No but may have helped instead of cramming the day prior. Just something to consider about getting a type rather than an ATP in light twin
