Advanced BioHealing Manufacturing Associate interview questions

Applied online end of Feb was contacted via telephone for a phone screening appointment. The appointment was set for a week later at 10am. Day of interview I was contacted one hour late by HR assistant to reschedule for 3pm same day. At 4pm I was contacted again to reschedule for the next day at 11am. I repeated the day and contact person's name to confirm and asked for a phone number to contact them. I was then moved to 11:30am within the same call. Next day at 11am I was phoned for the phone screening (scheduled time was 1130am). Screening lasted 45minutes. I asked a few questions and was never given a direct response nor a direct contact number, I was simply given the number of the La Jolla location which can be found online. I was contacted a week later in March to set up a second phone screen with their HR director for the following week, Tuesday at 1pm. I was informed that he was only in the office M-W. Tuesday 1pm, no call. I contact the office and no answer. I had hoped for an email or phone call by the next day but nothing. Still no response at all for the missed meeting or to my contacts. I'd say the interview was easy considering the first and only contact included information about my resume.
