Why did my friends and I get rejected for a Thai visa in Hanoi, and can we reapply at another consulate?

A user reports a rejection of their visa application, along with two friends, at the Thai consulate in Hanoi despite submitting a comprehensive set of documentation including a strong bank statement and employment proof. Numerous comments discuss potential reasons for the rejection such as missing recommendation letters, the need for a remote work letter from employers, and questions about their nationality and past work experience. Other users suggest applying at different consulates, particularly in Ho Chi Minh City, which might have a more forgiving process.
