What the job is is NOT a rhetorical question but is rather a real and practical question which you failed to answer and hence were not able to proceed further - in fact if you have read your pre interview emails you would have noticed that we told you that this question will be asked - and the fact that you showed up and were not able to explain what the job is (despite being provided with a very well detailed job description ahead of this interview) is pretty bad and it tells us that you don't know what job you really applied for and as such don't really pay attention to or think about things you do - and we don't want people like that, which is why we ask this question.
Also - regarding your comment on late showing of the interviewer - as it has been pointed out to you in the interview scheduling email, we run interviews back to back on dedicated days and as result we expect candidates to join the meeting room lobby at scheduled times and we admit them as soon as the interviewer finishes with the previous interview - and knowing that interviews run late - we warn you and other candidates in the emails that the interview may start ~10 min later than set - so you have no reason to complain, other than about your own lack of attention to what is sent to you.
I wish you luck in finding a job - but unless you change your approach you probably won't find one - interviews and hiring process in general is not there to entertain candidates - it is there to provide companies with good hires - so when you are getting a job, it is time for you to humble down and be gracious for the opportunities received and not behave arrogantly and with sense of entitlement.
