Preguntas de entrevista para el cargo de Senior Software Engineer - Java Developer en Ciklum

I was asked about a couple of past projects and then directed to a link for some simple find max questions but using Stream API. I explained the approach I will take and when noticing I don't even have code assist, I ask to be able to google the API since I didn't remember the map reduce specs for it. The interviewer laughed with scorn at me saying that if I need to google a solution as simple as that one he will end the interview right there. I explained I didn't have all the API in my head, and then he mentioned I may use Java docs. But the big red flag of laughing with scorn and playing the abort interview card was enough for me. I asked him if he really thinks I would want at that point to work with an interviewer that mocks the interviewee.
