You know I thought I was well prepared but felt like I fluffed the explanations to some of the questions. I also blanked when asked about the drawbacks to spanwise flow ... I got there in the end but had to be prodded.
So it went OK but I also wouldn't be surprised if I didn't get the 2nd interview.
As for study - Handling the Big Jets is a must. Also look at the gouge on jetthrust.com. Probably the one thing I would have done differently would have been to practice my answers outloud in a pretend interview setting in advance.
