TSD interview questions

Simple, they called directly for onsite interview where hiring manager and one Sr BA is conducting group interview, and Sr, VP validates it at the end of the interview. After interview i was so confident that it went so well and they will get me in but after 2 weeks of no answer when i followed up they send me rejection email, i think the reason of rejection must be the 1 question manager ask about salary requirement and i am sure mine was out of range, i still follow up that if it is just because of salary i am open to talk about it, but i never heard back. After reading 1 other review i feel that i am lucky that i did not received an offer.
