PTC Developer interview questions

Interviewed at PTC, Montreal office. Conducted by two employees from which one was a developer though he refused to ask any question since he thought the other interviewer was going brutal on me.

Process started with HR contacting me in reference to my resume on a Job portal. I had an initial phone screening with Technical manager where he asked about my current job & my experience in 3D graphics(This position was for 3D graphics programmer for CREO team), it went well & I was called in for face 2 face round which was an entire day process. The process started with an online test with C++ & aptitude sections, once I was done with the test, I was interviewed by a Senior Software Engineer with questions mostly revolving around 3D maths, efficeint way to sort an array, defining & usage of 2D arrays in C. Next round was with again technical manager which was more focussed on graphics programming & what was mentioned in my CV & the last round was with Director wherein I was asked about my expectations from the company. Next, I got the call from HR to come down to office for HR round & was offered the position.
