No, Arabic is not mandatory for most jobs in Qatar, especially in private companies and multinational organizations. English is widely used in business, education, healthcare, and hospitality, making it the primary language for most expatriate workers. However, knowing basic Arabic can be beneficial for customer-facing roles, government jobs, and enhancing workplace communication. Learning a few common phrases may also improve cultural understanding and daily interactions. While not required, Arabic skills can give candidates an advantage in certain sectors.
