Infosys Senior System Engineer interview questions

I got referred in the company by one of my friends. After a week, I got a call from Infosys saying that my interview is scheduled on that Saturday. Even though it was scheduled at 11, I reached the venue at 9 a.m. & I was called for the Technical Interview at 10 a. m. itself. I was surprised & checked whether it was for me only. In the technical interview I was asked questions regarding page life cycle, global.asax, caching, BOOTSTRAP( as I have worked on it) etc. Almost each & every point was covered from my resume. I guess they were verifying whether I have worked on all these or not. Some questions were out of my scope, to which I answered as I don't know the answer. Both the interviewers were quite supportive. They were impressed to hear that along with development I have knowledge of testing as well as project methodologies. I was told to wait outside. & after hardly 10 mins I got a call for HR round. Mainly salary & notice period were discussed there. I got the offer letter on 6th Business day where I was told that I may get it in 15 Business days.
