Castlight Associate interview questions

Applied online and had a quick turn around time setting initial interview with recruiter. Had two initial phone interviews, followed by a third phone interview. Interviews were very basic mostly behavioral questions and past experiences. Phone interviews were very enjoyable. After third interview I was told I would be called by hiring manager within a week, and what to expect when I have a in person, but after 2 follow up email with recruiter no response and was I left in the dark. Recruiters are very responsive for initial interviews, but after initial they are unresponsive.
