Hello, I have a job interview tomorrow and the job involves sending and writing emails in Japanese. I was wondering what the equivalent was for 'dear...' and 'yours sincerely' or 'yours faithfully'. Would it be 拝啓 and 敬具? or is that too formal for general business emails? Would it be more like: ◯◯さんへ and それでは, マーク●スミス。 ? Thank you!
