A male recruiter gave me a cold-call by the end of the day without any prior notice. His voice was choppy, probably due to a bad signal, so he called me from a mobile later. His attitude during the conversation was terrible, When I couldn't hear him clearly, I asked him to repeat his question, and he gave a contemptuous sneer, and he was constantly panting while I was speaking. I can barely feel any respect at all. This was my worst interview experience ever.
