PTC Senior Software Development Engineer interview questions

Applied on LinkedIn. Got a call from recruiter about the opportunity. He asked me to read a bit more about their products. Had a call with a tech lead about my experience and comfort at exploring new technologies. Got called for an on-site interview. Two days before the interview, they sent me a homework with 3D models. I was supposed to do something like Google Street view with it. I implemented a simple double click and move to Target. Interview process included: Brainstorming about the homework Behavioral questions White boarding (longest common substring) I got it partially correct but explained where I went wrong. The interview was on a Friday. Got an offer on Monday. Overall positive experience. I found people at PTC really, really cool! And the tech there is just beyond Iron Man Jarvis level!
