OYO Busineess Development Manager interview questions

I was contacted by a recruiter via whatsapp which does not feel like the right medium for it. We scheduled a phone conversation, but when the day came I was told they would call me 5 minutes later, than again some time later - I was waiting the whole day - but no one called. After scheduling an other day, I was called by the same recruiter, not being in the best mood. After three questions (to one of them they could find the anwer in my CV) I was told they would have a look on my CV (for the first time?). I thought the recruiter just wanted to have a look on it, but suddenly ended the phone call - without any notice. This was my worst interview experience ever so far. I felt not even appreciated as an applicant and the whole atmosphere of the conversation was just very bad.
