Though i applied online to a position in Microsoft for more than a month, i only received the call from the recruiter a day after i got a reference. Now though i applied for a Program Manager position, the recruiter informed me that my profile suited another position: SDET 2 among the current openings. I never did have any formal testing experience prior in my career but when the recruiter mentioned that development was the integral part of the profile. My interview was with a Lead Tester whose questions were excellent analytical questions in Testing scenarios. He did not ask any typical technical questions (which otherwise can be googled). He was really testing my thinking on how i would test a product.
