> Landing a job I don't know how to do 2/5ths of sounds awful. Then don't be an engineer? Seriously, an engineer's job is to invent new things that no one has done before, and tell other people how to reliably build more of them. If you start a project with a 100% clear vision of how to get to the end, then you are already behind your competition. Not knowing how to do 40%, and not being intimidated by 95%, seems like about the right mix.
