Same thing happened to me. I had 5 interviews with them and then nothing. I finally messaged the recruiter and still didn't hear anything. Messaged one of the people I interviewed with and they contacted the recruiter who them whined to me that she had sick kids and didn't check her email. Over a two week period she didn't check her email? Give me a break! By the way 8 months later they are are still advertising the same position. I don't know what their problem is but glad I didn't waste any more time on them.
