CSP Music Group review: It's strange that you need to pay for the interview

The company CSP Music Group posted the advertisement about the job and I filled couple of forms and provided a lot of personal details as well as my photo. I got the email back, where they asked to fill the appointment for the interview and said to pay now with the card. I gave them my credit card details as well. I don’t know, but it seems strange to me that I need to pay for the interview and their shortlisting was so strict.
