AirlineApps tip: (to add to TED74's rec)
In the job 'duties and responsibilities' block, (the way you see it while filling it out) it looks like only enough room for 1 or 2 lines. In most cases you can type in more info and it'll expand when you view/print. The boxes actually hold 6-7 lines of text when printed. The problem here is that you can't tell, while you're typing, where it'll cut off; it would let you write a novel if you wanted.

I recommend typing your job descriptions into Word/Pages and let it spell/grammar check it for you. Copy it and paste it in the box, then go to the end and click the view/print button and see where it cut you off. Go back to your W/P version and see what you can trim without loosing the important stuff.

I'm sure this would be covered by each of the interview prep services, but I thought I'd mention it in case you're not to that point yet.
