Virtusa Project Manager interview questions

I have posted my resume in a reputed Job portal and applied for Virtusa. After that I got a call from Virtusa HR detailing about the company and the current requirement they have and asked about my interest. As I showed my interest to pursue, HR have arranged for a Telephonic technical discussion, which went for 30 minutes. In a week time I have been called for a Face to Face discussion with senior management which went for 20 minutes followed by HR discussion which went for 40 minutes. During HR discussion I was asked for some technical & scenario based Questions. (I dint see that coming, it’s a surprise to me to answer technical questions, explaining OOPS concepts and so on. Normally HR discussion comprises of Current designation, Expected designation, Current CTC, Expected CTC and attitude of the candidate). At the end of the HR discussion, I was informed that I will get my offer in 2 days time with a decent hike in my salary. (HR hasn’t given me the exact figure of CTC they are going to pay me). After a week, I have received a call from the HR (who had coordinated this recruitment) to convey my Designation & Salary and asked for my interest to take it up. I was not happy with the salary proposed by the company. After a month of Salary Negotiation I finally accepted the offer.
