Did others also face this, or was it just me? It was completely unprofessional.

My interviewer was horrible. He didn't introduce himself or Google.

He asked about me and barely listened to my answers over the telephone. He quickly posed very difficult questions and seemed to be doing other tasks simultaneously.

Whenever I asked anything, he would just say, "Good, proceed, right approach," and then disappear.

Finally, I was rejected.

The questions were about grouping vocabulary, and I was unable to even search on Google for what he actually meant or asked.

At the end of the session, he said "thank you" and disappeared with negative feedback.
