I got the Qualtrics survey, too, and since it contained a lot of information about the white coat ceremony, I'm thinking it's only for people at the Chicago site. I also don't know what you mean about being assigned to orientation. Pretty sure that orientation is August 10th and August 11th with Task Day on the 9th (and I don't even know what Task Day is tbh). I called today about the HIPAA, OSHA, Respiratory Fit Test, and Influenza requirements on the CastleBranch website, and it looks like there's been a lot of responsibility turnover across departments in terms of who should be informing us about the specifics of those requirements (along with the drug screen). They said they'll be getting back to me ASAP with any information about it, so I'll relay it here if I hear anything else. I also plan to get the drug screening done through my primary care doctor.
And that's definitely just paranoia. You're in.
