PTC interview questions

test + technical +HR The interview was offline at the PTC Weikfield office at 10 June 2023. I was interviewed by two different persons, one asked me questions related to my resume and the other person asked me questions related to CS fundamental subjects. The interview was around 1 hour and 15 min. There are different teams(Creo, Windchill, Navigate) at PTC, out of which I was interviewing at Windchill. The interview started by introducing myself.

First they show me some functions in C and asked me to find the problems and fix them, and then some coding questions to solve in notepad. Interviewers were very nice and calm. Gave a good feeling.
