It is very unethical process. I rejected multiple time and everytime they convince to be open for this opportunity. I have cleared first round. For second round, they made me wait for 1 and half month. For third round, almost 3 month. I understood referral politics is going because India undoubtedly have nepotism problem. Anyway, in third round as per my job description. I prepared for network, basic of browser of memory and caching along with HTML5 and web development. Since, I already dropped email because I sensed there isn't any reason of delay especially company like microsoft. In this round of interviewed they start asking question operating system, I told him I don't prepare for OS also I have experieced in support of debugging windows along with networking. Also, I am comfortable in Linux. I don't remember much of OS. Also, it is not mentioned in the job description then interviewer said it is just basic of OS. Anyway, he started questioning x86 computer and bus. Then on MMU asking question on memory loading and unloading. I understood interviewer was screwing me. I quit the interview by telling I applied for job as per JD. I knew something fishy about interview. Anyway sums up, microsoft isn't a goodcompany and company has been hijacked by nepotism. I will mention First wound of question.
