A2A. Sorry, I have no first hand experience with this.
But, I don't think that they should care as long as you have a B.Tech. degree. As long as you have knowledge and good grades in your B.Tech., Google couldn't care less whether you did a diploma or 12th.
This is my opinion, not a fact, because I don't have first hand knowledge. But, it seems logical that they shouldn't care.
I like to blog about various topics ranging from education in IITs to social issues in India and US. All opinions and views presented here are my own and not of my employer.
