Preguntas de entrevista para el cargo de Java Software Developer/Software Engineer en BlackRock

Applied online. Straight into a technical interview with 2 engineers. The first half of the interview comprised of some Java-related questions (Strings, OOP, polymorphism), and the second half was a small coding task. The second interview was another technical interview with a couple of engineering managers. This one was more of an in-depth conversation about my experience and skills.

I got a Hackerrank Coding challenge(3 Programming questions) which I finished on the weekend and sent back. They were happy and scheduled a programming interview with a VP who was so unprofessional . First off, he came 10 mins late telling he was in the middle of a production issue and he can give me more than 30 mins to complete the programming challenge. I took 35 mins to complete. He was dead silence all through the interview. He was working on the production issue and not paying any attention to the interview at all. I kept asking him to ask any question if something is unclear. He didn't ask a single question. At the end he mentioned that he made up for the late start by giving me the five extra minutes. I passed all the test cases and the next day they mention they are not moving ahead with my candidacy. I am not sure what the reason would be when the interviewer didn't even pay attention to the interview. What a waste of time. I spent a total of 3 hours. The HR was good so my review is not for the Organisation as such.
