Ask HN: How do you find industry research internship?

I am on my final year of my Master's studies, and I want to intern as an industry researcher in CS-related field. I currently take Web Science where I do network analysis, and also have a degree in Sociology. I also have been working as a web-developer, and currently doing work student job as a web-analytics implementer (nothing fancy).

I tried looking into the few big names (who have international research labs) as I am based in Germany. I applied to Microsoft; Google's intership is closed for this year.

I place where I think I can contribute and learn more would be a company with lots of social data such as FaceBook, Twitter, however, to my suprise, Facebook doesn't seem to have internship projects with social science and computer science background. Maybe a company with a core marketing front?

I wanted to ask how did the HN community find their way into industry research internships or positions? In Europe? In USA?

Where should I start looking it? Are there specific job boards for such kind of positions? Any advice would be super super helpful.
