I applied online. I interviewed at American Alpine Institute
Interview
This was 5+ years ago now... but did a 30-minute phone call with Dunham (owner), where he went through my application, spoke about my background and guiding/climbing experience. At the end of it, he said I got the job and if I could be there in 10 days - time to pack the car and get to Bellingham! (I had applied only a little while before the interview - it wasn't their fault for the short notice)
Interview questions [1]
Question 1
# of glacier routes completed, biggest/most difficult rock, ice, mixed, alpine climbs done to date, how hard I can comfortably lead in boots, rock shoes
