informal job offer ceremony; orientation for new graduate hires
A formal event held by Japanese companies, typically in October, where students who have received an unofficial job offer (内定) gather to receive official documents and hear speeches. It marks the transition from student to prospective employee.
I bought a new suit because I have an informal job offer ceremony next month.
内定式では社長の挨拶と内定通知書の授与が行われた。
At the ceremony, the president gave a speech and handed out the official job offer letters.
