Is Beard allowed at Ras Tanura refinery- have an interview n

Hi All,

I got an opportunity for an interview (next week) with Saudi Aramco for the job alocating at Ras Tanura Refinery and wondering if there is any any restrictions for having beard on face? I know in Canada, someone must have shaven before visiting the petrochemical site. Please advise ASAP as my interview is next week.

Secondly, Can some guide me about the types of engineering interview questions being asked?

thanks in advance!
