Interviewer sounded condescending, loads of technical questions and a few expected questions on the company and the candidate's interests. They pinpointed on certain experiences from my resume for me to elaborate on the technical aspect.

Supposed to be a HR screening call, was told I did not need to prepare anything, but it turned out to be a full-on interview with HR, with typical interview questions. Also was asked if I understand the responsibilities of the role and what clients the company typically work with (this was supposed to be a screening call?)
