McLeod Centers for Wellbeing interview questions

I wasn’t able to go through or experience the interview process due to no effective communication. I was contacted for an initial phone screen for an Health Informatics position from an automated ADP email address from this company, which I thought was odd because I'm not aware of employees or departments usually contacting candidates through the ADP system or having the ADP system as a way of contact as this was the first, for any employer. I thought it was just a payroll or job application processing system so this was the first. I was also taken back as the human resources professional didn’t provide their work email address, to contact if any issues in the interview process happens to occur. I guess the whole people operations department shares one email address. I was sent an calendy link to set up an initial phone screen and when I clicked on the calendy link the calendy said no times available. I was sent an inefficient link with no available times. I thought maybe at first, giving the benefit of the doubt it was a technical difficulty but as refreshing the link and clicking on the link numerous times and trying another date, the calendy link still had no available dates, which I didn’t understand as the email wanted an initial phone screen that specific week. I contacted the email that contacted me twice to discuss the issues and received no response. I even contacted the Human resources professional on linkedin to discuss the issues and still no response. I came to the conclusion that the email address from the entire People Operations department might have been just an automated email, as to why I couldn’t see the available times on the calendy link or receive a response from the ADP email address. I believe having a streamlined, efficient and effective interview process is important and it;s disappointing being contacted by a company that doesn’t have that, getting hopes for a potential job up.
