Recruiter set up the interview via Skype. there was no introduction or even small talk. when i said that i can't hear him he replied rude and said he will call me back. I couldn't hear him very well because he was driving somewhere. I lost in thoughts when i spoke to this person. Recruiter used too many abbreviations. It is very common to hear but I would expect that recruiters use the full language. The interview went very unprofessional. I wish i could talk directly to the hiring manager.
