I applied through a staffing agency. The process took 3 months. I interviewed at PTC (Pune) in Feb 2017
Interview
I was approached by a consultancy through my profile on an online job portal.
It comprised of total 6 rounds.
Round 1 - Nov 2016:
It was an online coding round on HackerRank with 10 MCQs and a couple of simple coding problems.
Round 2 - Nov 2016:
It was another round on HackerRank but offline, was given an implementation and was asked to refactor it by following SOLID principles, the time limit was 3 days.
Round 3 - Jan 2017:
This was a Skype-based technical interview round, some strongly analytical and approach based question were asked related to my skill set. I was told by the interviewer to come for the F2F interview to Pune.
Round 4 - Feb 2017:
Reached Pune at their office, this round was purely technical and some very good questions were asked related to Java (my strongest skill set),
Round 5 - Same Day:
This was a discussion round with the Project Director, more of a get to know type of round, told me about PTC, my team as well as the role I was going to be offered. He told me that he will be recommending me to HR department.
Round 6 - Same Day:
This round was an HR round, with the typical HR discussion and concluded with a successful salary negotiation.
Overall I am pretty satisfied and happy with the process, the interview process was really meeting standards of a product based company.
