Poppycock. You don't neeed to work 10 years in some investmennt bank dungeon programming to know that stuff. You can "self-learn" computer science and you can answer that stuff without much problem. I was more than familiar enough to answer those questions before my junior year in college and really I was close to getting a handle on concurrency, at least to answer the superficial questions that get asked in an interview, before I entered college. If you follow programming languages, the type inference and covariance, etc is not a big deal. In fact, I wouldn't think working for an investment bank is the way you go to learn that.
