Wipro Analyst interview questions

My resume was shortlisted and telephonic interview was conducted after which I was called to Bangalore for GD & Interview. I cleared the GD too but in interview they said that sorry we are looking for a B.tech grad as this is a technical position. I didn't get that why have they shortlisted my resume when my qualification was clearly mentioned in the resume further being a Btech grad is not a licence of being suitable for technical position . Employers seems to be really confuse.
