BluePrint Research Group interview questions

1st round interview was fairly simple, CV based. However after that I did not hear from them, I was told the assessment centre would be on a particular date so I kept in free in case. They did not send me a rejection email, rather I had to chase them up asking for an outcome. Very unprofessional.

I sent my CV and cover letter, and was invited to a phone interview a week after. The interview itself was competency based and not so difficult. I was told in the interview, that the assessment centre would happen on a certain date so I kept the date free just in case. Three days before the assessment centre is due to take place, I still have not heard anything about the outcome. I send emails and calls to the company, however they are unanswered, finally I manage to get through to the HR manager who tells me my application has been unsuccessful. No feedback at all was provided, just a generic 'good luck with future endeavours'. Applicants should not have to hunt down a contact address in order to track the progress of their application. The experience overall was unprofessional.
