My toughest job in English

I've had some a hard and an interesting job lately. It took almost all my free time for a week and a half. I'm telling talking about the decoding of an audio interview.
When my friend offered this job, I thought "Well, sounds interesting. I have no problems with English listening of to English BBC podcasts so why not?". Then my friend said "It's about a 60 minutes interview with a punk band from Portland, are you sure?".And I thought for a second time "Hmm, It sounds as like a challenge and I can learn something new. Of course I should take this job!". My friend gave me about a week - a week and a half, and I started to do this.
Oh, God! I met really serious problems with pronouncing and understanding of words I've never heard. In addition the members of this band from Portland were telling talking about other cities and states of America, they were using some specific words and phrases and I didn't know neither US geography nor those words well.
Thanks to Google and Vocabulary.com they which were very helpful to me, and the speed of my decoding increased with them up to 1 minute of interview per half an hour of my time! I know, it is not very quick and some Italki users have their own tricks and know other web-resources and their speed can be more quick quicker, but I did it!
Of course, after all my friend did some corrections of my job, and I heard some jokes about ridicules (ridiculous?) moments in my text, but I gained some experience in English and it makes me feel happy now.
