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.
