I interviewed at SKW a number of years ago after ACA went TU and I was working as a sim instructor. So off I went to SLC for my interview. HR wanted to know how many times IN MY LIFE that I called in sick. What?!
Then the interview CA...The guy was seething of artificial niceness, and started out by asked me this question "You just broke out on an ILS at minimums, how many stripes do you need to see on the runway to know you have legal visibility?"
I wasn't too happy about playing the game, and my answer was rather flippant. "Well, it's been my experience as a 121 captain that if I see a number on the ground, and its the same as the one on my approach plate, I'm not counting stripes, I'm landing on it. Besides, it's pretty assuming I'd know this as not all ILS approaches end at 200 feet". He didn't like my answer (surprise).
Then the next was "Draw a winglet and the airflow around it". At that point, I knew they were already done with me, so I just said something to the effect of how the winglet worked but that I wasn't a good artist and that to draw it would be rather foolish as AOA, speed and winglet design will slightly alter the flow (again, not really the best way to answer). I just didn't like the way that the guy was carrying himself at me, all 24 years old of him and his "big" 2000-ish hours. So I guess you could say I blew it in a matter of seconds. But really, to treat an experienced guy who was going to start over at a whopping 18 bucks a flight hour, they should show a little more appropriate questioning than the usual "stump the applicant" game that they do to a new guy who is begging for his first job.
I did nail the sim though. Very easy ride. I liked the sim guy but I'm sure that the decision was made long before I got to him.
Needless to say I was not hired, but I didn't really care. It looked like a good place to work, I just didn't want to play the begging game. Things ended up better in the long run for where I am now.
Moral of the story....don't let one interview get you into self-doubt.
