Digital Prospectors interview questions

I was contacted by Digital Prospectors for a contract position with a Pharma Company. First was a series of phone interviews and a final in-person interview with the Pharma Company. Very easy process.

Immediate phone call screen went well, group interview within a few days went well, then over a week goes by with no response. After I sent a f/u email, I got a curt response that they changed the position and were searching elsewhere. Typically companies let you know they are going in a different direction and this felt unprofessional.
