1 hour call with the hiring manager was the worst. She clearly was v poor at conducting an interview. 1. Jumped right into it without even making the candidate feel comfortable. 2. She seemed pretty annoyed when she didn't get the answers she was expecting (and these were the questions based on my past experiences) 3. She explained me a business problem and expected a solution from me as a part of the interview but she seemed pretty annoyed when she had to explain me more than once. Its not the case of "grapes are sour" with me, the business problem was something I have never dealt before, and she would have understood if she had gone through my resume thoroughly. I felt humiliated when she made me look like a fool for not solving a "very simple math" problem.
