I've just been hired to be part of a group that is developing in C++. Before, I've been coding on and off at my job for the past 11 years (some C, some Fortran, some C++).

The coding I've done was mostly maintaining and adding new features to one of our systems. The code, being 10 years old, did not contain all the modern C++ stuff. Lo and behold, my new job is filled with programmers with 5-10 years experience of pure coding and they all use the most modern aspects of C++ (C++11, template, lambda, etc, etc). They are expecting someone with that same experience... Well, I've been working for 15 years total but when I looked at their code, I couldn't understand half of it! :-|

Anyone been in that situation? What would you recommend?
