When you did the application, did you say you had more time than you actually had? I have heard of folks getting called out of the interview and sent home because they check your logbook against the date you did the online application. If you checked the "yes" box next to where it says "Do you have at least XXX hours?" but in reality you didn't but were expecting to have that by the interview you may be in trouble.

Hope that isn't too hard to understand, I had to read it over a couple times to make sense of it and I wrote the thing Bottom line: its not worth risking a black mark like that just because you can't wait the 2 weeks it takes to build your 10-20 hours to meet the mins.
