Hitachi Digital Services Java Full Stack Developer interview questions

I attended two technical interviews, the first one was good and the questions were professional and related to the job, but the second one the guy was in rush, unfriendly, and rude, and he asked questions that were very detailed and specific to specific scenarios, and you solve those problems by debugging and checking logs and here is no specific answer for those questions, like if the server sends "trying to connect" what would you do? and I said I would check the server status and the logs to figure out what is the issue, and he didn't like it!! If Hitachi doesn't want to hire people , why wasting people's time and energy??
