Arm Senior Python Developer interview questions

After applying for a position and being discarded, I was contacted for another position focused on Python programming of validation and testing scripts. No one shows up on the first date because recruitment had communicated to the interviewer a different time than mine. Unfortunately I could not do the interview at the time they wanted. They thank me for the collaboration :-| then we agree for another day of the following week. For the interview I had reviewed some Python fundamentals (even if I work every day, a review doesn't hurt) but the interview only revolves exclusively around C ++, the C ++ compiler and real time operating systems and not. All topics on which I am prepared, but which I would have liked to review before the interview as they were part of my cultural background of previous work experiences. The interview was pleasant, interesting, and the interviewers were nice, anyway I didn't turn out to be up to the role and it's a real shame, because the topics covered were very interesting, but unfortunately I wasn't able to excel enough during the interview. The recruitment emailed me the usual copy and paste email, no feedback that can help you understand what topics you need to prepare better.
