Received email from HR, contacted HR following day left message as they were unavailable, followed up with email that I had left voice mail. Instructed to call next business day, unavailable, they did return call, interview set up with specifics where to report to. Arrived 20 minutes prior to appt & checked in, receptionist did notify I had arrived, 20 min passed, receptionist came out & apologized, took me upstairs to a different location, informed person I had been waiting. 15 min after scheduled time, interviewer arrived. He did not appear focused, in my opinion situational interview questions presented were vague & missing content. When I left I discovered a missed phone call from employers phone number. I have not yet verified who the call was from, missed call was 3-5 minutes before interviewed showed up.(suspect it was from the interviewer) wondering if there was a lack of follow through to notify interviewer I had arrived, & he was calling to ask if I was still coming? I will be following up on. Lack of communication between employees.
