I applied online. I interviewed at PTC (Boston, MA) in Jul 2020
Interview
The interview process was very rigorous. But, although my interviewers really grilled me, they were friendly and respectful. Also, I had 4 rounds of interviews:
1. With HR (more of a phone screening)
2. With the hiring manager
3. A panel of 3 team members
4. With the hiring manager's boss
I'd say, the challenge of the interviews has matched the challenge of the job so far.
i had a first interview, 3 hours long , all the questions can be found on the internet. i answered all the question but didn't get an offer though. good luck!
