I applied through a recruiter. The process took 2 months. I interviewed at PTC in Jan 2017
Interview
Recruiter screening, then hour long phone interview with the hiring manager, finally, a 2 hour group Webex Interview. I was required to give a presentation during the group interview describing a project/program (no proprietary information) and have a Q and A session during and at the end.
