Luckily for us, the regionals nowadays are very motivated to hire you, and getting an interview basically is just a matter of meeting the time requirements. The only work you have to do is come prepared to the interview.
A few things to look at when choosing which company to go with are:
Upgrade time - although this number is very dynamic, you don’t want to go to a company that has a 10 year upgrade. After all, just like flight instruction, you want to get the hours and move on in the least amount of time.
Reserve time - just like upgrade time, the faster you can get a line (a set flying schedule for the month), the more time you will log.
Domicile options - You work half the month, the other half is time off, spend that time off in a place that you will enjoy. Also, commuting to work, especially as a junior FO at a regional, can be a nightmare.
Pay - make sure to check not only the hourly pay rate, but also things like deadhead pay, minimum monthly guarantee, minimum day credit, per diem rate, profit sharing, benefits, etc.
Quality of the lines - it makes a big difference if you credit 20-30 hours on a 4-day trip, as opposed to 10-15 hours.
Those are just a few things that I considered when choosing a regional to fly for, but that’s just the tip of the iceberg. As you progress with your flight instructor career, should you choose to accept it , you will get a better understanding of what to look for.
I know I didn’t know most of this stuff before I started flying so feel free to ask more questions if you want more details on what I explained above.
