Palo Alto Networks Embedded Software Engineer interview questions

Referral from an employee. Had a talk with recruiter and initial 45 mins round was scheduled with hiring manager. Hiring manager had an abysmal interview skill. Asks question as if he is barking towards me with total impatient tone, overall arrogant and mean. I am sure to get a rejection but even I would have gotten an offer, I would gladly reject it than working under that guy.
