This is not at all unusual and certainly not unique to Lilly.
I recently applied for a job with AstraZeneca. Interview with external recruiter, interview with hiring manager, one of two people to go to an interview with another manager - then nothing. I followed up with the recruiter and even the recruiter didn't reply.
Last year I applied for a job with Microsoft. They got back with the thanks-but-we've-restructured call four months after the interview.
And in January 2009 a company offered me a role which I had interviewed for in February 2006.
Not calling back, taking their sweet time, whatever - it's hardly unique to Lilly. It's normal.
