I know more about c++ than c#

I blogged about exactly the same thing before ...

Here's a paradox -- i spent 2 years in a full time c# job, arguably longer than my full time c++ experience. However, sometimes I feel I understand dotnet less than C++. Reason? Many aspects of the languages are never used in-depth on work projects, so length of experience != depth of experience. We need spare time self-exploration to learn those aspects like:
- template meta programming
- custom operator new/delete
- memory tuning
- memory leak detection
- threading
- async communications
- pure virtual
- ++i vs i++

(... not a complete list by any measure.) Interviewers are notorious for testing these obscure or advanced, theoretical topics.
