You never know for sure, but I believe this happened to me. I had a follow up call with HR about why they weren't continuing with me despite what felt like a good "getting to know you" introduction interview. The gist of the answer was "we feel that you are in range of [some job level/position] but only the very senior people in that department are paid in the range you mentioned as your requirement." So they decided not to spend any more time with me because of the mismatch of salary and their perception of my experience level so far.
