Korean corporate culture is inspired by Confucianism and Japanese corporate culture. Some very minor aspects of American corporate culture have also been adopted in Korea. Koreans consider that their company is an integral part of their identity. Korean companies have army-like titles for workers where workers get promoted. Koreans start off as "sawon" when entering a Korean company, meaning "grade 1 worker" much like officers in the army, before they go up all the way to "depyo", much like generals in the army.
Applying for a job in Korea
Unlike American companies, Korean companies discourage applicants from applying via email or by mailing applications. Though these days some companies allow electronic applications or applications sent via mail, many don't.
To apply for a job at a Korean company, one should go to the company headquarters with a sealed envelope containing a resume, a cover letter (called self-introduction letter in Korean), but also medical records, grade transcripts, pictures and copies of diplomas. The sealed envelope is then left either at the reception desk or at the human resources department.
