Dress Code for Sales / Marketing people

Assalam Alaikum,
Counting days to move into Jeddah probably next month, Insha Allah.

Just wondering what is the office dress code for sales / marketing people in KSA? I know its hot, do people still wear coats and ties?

Though it must be variable between employers, but what is the general rule of thumb?

Anyone, please?

Actually it's like anywhere else, it depends on the employer /company policy and sometimes personal choice, so it range from casual/smart casual to tie and shirt even suit
