I found it hard to figure how my resume could summarize the breadth of my knowledge. I ended up putting a table up with "Good knowledge of", "Some knowledge" and "Worked with" in my resume, listing each skill under one of the three headings. Gives a pretty general idea. Then again, during interviews for the job I'll be starting soon no one asked me a single technical question.
My reasoning of that is that it's a two year "traineeship" (widely used term in the Netherlands, seems less so abroad), which is more of a dive into the company, with extra coaching and mentoring at two different positions within the company. Most interview questions were of the sort "how do you work in teams" and "where do you see yourself in 5 years" - much harder to answer than technical questions :)
