Job Change Consulting in One Hour! We’ll cover the essential information you need for a career move, including resumes, cover letters, reference checks, and salary negotiations. 1. Resumes and cover letters. They may not seem like a big deal, but they can become surprisingly challenging tasks. 2. Salary negotiations and reference checks. They may be unfamiliar experiences, but you must prepare for them. 3. Your career is not limited to your workplace. For 23 years, I have supported the career moves of juniors and seniors, colleagues, and employees of client companies through my experience as an office worker, Secretary-General of the Federation of Foreign Investment Companies in Korea, and consultant.
