First-hand accounts from people who interviewed at PTC.
Software QA Tester
The hiring process began with an online assessment on the Mettl platform, accessible from May 11th to May 21st, 2023. This test had four parts: 15 MCQs on aptitude, logical reasoning, data interpretation, and English; 20 MCQs on Java, C, and C++ programming, focusing on predicting code output; 10 MCQs about SQL queries; and 5 MCQs on Software Testing. Following the assessment, there was a technical interview held offline at the PTC Weikfield office on June 10th, 2023. This interview lasted about 1 hour and 15 minutes and involved two interviewers. One focused on questions from my resume, while the other covered CS fundamentals. I was interviewing for a position within the Windchill team, distinct from Creo and Navigate teams. The interview started with a self-introduction.
- Can you explain what a process is?
- What is the difference between a process and a thread?
- Could you describe the various types of memory?
QA Engineer
For the QA intern role, the first step was an aptitude test that included quantitative ability, verbal ability, logical reasoning, and programming MCQs in C++ and Java. It was quite challenging, and only those who really practiced aptitude tests could pass. After passing the aptitude test, they called us for an in-person interview, which was purely technical since it was for an intern position.
- Can you sort an array in descending order?
- Explain Bubble sort.
- What is SDLC?
Senior Quality Assurance Engineer
The interview process was quite long with several stages. I had another offer so it gave me more confidence. First, there was a recruiter screening call (not counted as a round). Round 1 was a telephonic interview with the interviewer, covering basic skill questions; the goal was to exceed expectations. Rounds 2 and 3 were in-person interviews with development managers and leads, each lasting about an hour, focusing on tricky questions designed to see how you handle situations professionally. Technical questions were a bit challenging. Round 4 was a final discussion with the director, not a typical Q&A, to confirm suitability for the role. I did a lot of research on the company and role beforehand. I was nervous during rounds 2 and 3 due to being new to in-person US interviews, but researching the project helped provide talking points for the final round. It was a worthwhile experience, helping me focus on interview mistakes. I believe I got the offer and signed it. It was one of the best interview experiences, keeping me engaged without repetitive questions. If you're not on H1/L1 visas, you might start in a couple of weeks.
