Accenture Salesforce Developer interview questions

Accenture hr contacted and arranged the interview. Bad experience with the hr during interview schedule. They didn't ask for the availability and reschedule, cancelled the interview. 1-2 months after the call another interview was scheduled. Interviewer asked questions around below concepts. Interview took place for around 10 minutes. Answered almost all the questions and was expecting for call back as there was no rejection email on the same day. But after a day they sent out rejection email without proper reason.
