Mayo Clinic Speech-Language Pathologist interview questions

I was very impressed when I spoke with my interviewer on the phone, and excited. I was not told upfront that it would be not 1, but 3 in person interviews which was disconcerting. The interviewer was friendly and professional, but it felt as if the interview process and the entire place was very secretive. In addition to the 6 hours of interviews, I was required to submit writing samples which totaled 8 pages (one MBS report, one tx report for language patient, one for a cognitive patient, one assessment report for dysphagia patient at bedside. All of these were to be written fictitiously of course so it took some time, etc.). I was also asked to provide 3 letters of recommendation on top of references. OUTrageous! I had to ask how many more interviews after the first, and had to ask when I would hear back. I was given a date. That date came and went. I heard nothing for well over a month. I e-mailed once and left a voicemail once during that time politely requesting a response and heard nothing. I was incensed! After 6 hours spent interviewing, providing everything else that was over the top and asked of me, it would be decent to return a phone call, or to reach out personally and say it wasn't a match rather than send an HR e-mail: Thank you for applying to job number XYFU but it has been filled. Later learned they have cameras everywhere there and voice recording equipment so if you swear or do anything unprofessional you are recorded. Not the place for me, so I'm glad I didn't get the job now, but wow I never want to go through that again!
