PTC Senior Software Specialist interview questions

HR team was very prompt. The entire process from first call to salary negotiation was completed in a few hours. I was called for the interview in PTC Kalyani Nagar premises. Went through 2 rounds of interviews, both technical with increasing difficulty level. Second round was a mix of technical and managerial. This was followed by an HR round for majorly salary negotiations. Offer letter was released in 3 days.
