I've already had several interviews and now have been waiting for a month and a half for a decision. All this time the recruiter has been telling me it's positive and she's just waiting to hear back from HR. Monday she emailed me it was still very positive and she should have a positive update for me shortly. She mentioned she'd call me either that afternoon or the following morning, however she still hasn't called me. Is it too soon to email her for a follow up?
