Clinical Resolution Laboratory interview questions

It was a pretty standard interview. I was brought into a conference room on the 2nd floor and spoke with HR I believe. It was a little on the short side but most things were self explanatory. After the interview I was sent a design challenge, which is a polarizing topic since it's free work. The message was addressed to someone else so I was a little put off by the lack of detail for the interview process. Thankfully I found a different position as I notice frequent listings of this position.
