Abbott Director interview questions

In August of 2015 I applied for a Director level role thru their Career site. A recruiter kept me "warm" for 2 weeks and then talked to me for an hour, followed by interview with hiring manager for another 75 mins. They said "its a great fit and we would really like to go further with you". Then total silence. Neither the recruiter nor the hiring manager would return email messages with any information as of today, Feb 2016. I wonder why a company of Abbott's reputation would behave so poorly.
