The interview process here happens in several stages. The first stage is the initial application. Note: you may be asked personal questions about your health status, which may be uncomfortable for some. After you hear back from the application, you are asked to upload a video of yourself answering a few questions. The next stage of the process is an actual interview. After that, you're asked to do a series of homework assignments. I can't remember the exact order of them. One is a presentation of a problem, and you come up with solutions for your methods with an explanation of why. At some point, you also scope out qualitative research and write a discussion guide. Finally, you hold mock interviews with patients. After this, you write up a report. I'm not sure if the interviews are truly mock interviews or if they're for active work ongoing at the company. At least one was definitely just a mock interview.
In total, I believe I spent around 10 hours on the application, homework, interview with the company, interviews with the patients, and report writing. This is the most time I have spent on an interview, and I would not have done so had I not been passionate about the mission of the organization. In the end after the final written report, they ghosted me. Being ghosted after the time commitment and interviews with the company makes one think twice about their core values, especially being people-first. A standard copy/paste email for candidates who make it to the final stage should be easy enough, such as: "Thank you for your interest in the ___ position. Unfortunately, you are no longer being considered for this position. We thank you for your time during the interview process and wish you well in your future endeavors."
