This is not one of those questions like "How do I learn Java extremely fast, I know nothing about programming, but I heard Java is cool, yo".

I have an interview for a Java Software Developer in a couple of weeks and the thing is that I think that I know C++ really good and I am somewhat good at C# (like, here I can probably answer on a lot of questions related to these languages), but I have almost zero experience with Java.

I have a lot of projects written in both languages, I participiated in several open-source projects (mostly C++, though).

Now, what should I do (in your opinion) to prepare myself for this Java interview.

I guess migrating from C# to Java should be kind of fast, especially when you know a lot about programming in global, patterns, modern techniques and have a lot of practical experience behind you.

But still two weeks is obviously not enough to get Java in-depth - so what should I focus on to have the best chances to pass the interview?

Thank you.
