Discovery Health Partners interview questions

I was initially interviewed by the HR recruiter. I then was set up to interview with 3 other employers including department managers and legal department. A couple days later I sent an email thanking them all for taking time out to talk with me. A week or so after that I requested a status on job placement. I never heard back from anyone. I never got a decline email, letter. It was as if I didn't exist to them, like the interviews never happened. I find that very unprofessional of a company who can't respond with a simple "you weren't selected" email. I applied for multiple positions within this company. All of which I was overly qualified with experience. I felt the interviews went well. It's impossible to know what I need to improve on when you hear nothing back. Very disappointed in the whole process.

After submitting my CV, I was contacted over email for an aptitude test. I received feedback that I passed the test a week later. A interview comprising of a series of questions and then a role-play scenario using a phone was done.
