My slot was around 7:30 pm . I went and took a nap in the hostel. When i reached at the venue ,the candidates who went before me said that the questions were from Compilers and Operating System. I was good at Algorithms so i planned that i will proceed accordingly. As expected the interview started with the interviewer asking me about my project . Which was in an abstract mode at that point of time , and it was a new field of development my interviewers didnt had much clue about it so i passed that without many questions. Then from my resume they knew about my interest in Algorithms and programming so logically many questions followed which i answered. Then suddenly they started asking me questions from Graphics , things like face detection and depth calculation etc. I was just prepared enough to answer them . Then they asked me a question on Graphics and asked me to propose a solution . The question was how can you tell that whether a point is inside the circle or outside it . I started answering with using fundamental geometry but he wanted a much simpler answer where i finally arrived as i was allowed to query the pixel color so for the point to be inside the circle , i will have to go through a transition of pixel where i will first hit the boundary color then the pixel color then finally the boundary color.(I told them that i will use a rastor scan). I believe that the way i answered it sealed my job chances , because all the questions which followed were straight concept based and you could really answer it easily if you have done some preperation.
