Autodesk Developer interview questions

I applied through LinkedIn and got a call from their HR. The role was C++ based. 1st round was telephonic interview where I was asked questions mostly C++ OOPS concepts, STL and smart pointers. I was scheduled for a F2F within a couple of days. There are 2 FTF interviews where 1st is more of technical with C++ OOPS concepts, DS and algorithms, STL, constructors, one logical programming question and one puzzle. The questions included basic maths and geometry concepts to solve. The 2nd interview is more or less technical+HR based. The interviewers give enough time to listen to your approach and are also ready to help in you in the right direction. Make sure you revise basic maths and geometry concepts regarding vectors, transformation matrices
