I've left two voicemails so far to the nurse manager in charge of the floor I am trying to apply a job at. HR already sent my application almost a month and a half ago and that is when I placed my first voicemail before I went on my 3-week vacation. I called again when I got back, but found out she won't be in until June 1. No return call yet. Should I keep on calling? or is this a sign she doesn't want to hire me? I really want this job (its med/surg).
