I applied through other source. The process took 1 week. I interviewed at PTC (Needham, MA) in Jan 2012
Interview
My initial contact was an email from my point of contact at the company. I then received a call from the person who would be my supervisor. Questions included what PTC does, its role in the industry, my experience with PTC, my prior experience with similar software, as well as my ideas of what I would bring to PTC. After the call I received a follow-up call with my offer.
Interview questions [1]
Question 1
Honestly the most difficult part of PTC's interviewing process would be describing what PTC does and its role in the industry.
