Why do I volunteering at IITTI?
Short answer: Employer Branding
Longer answer: IITTI is a standardized test in professional image and etiquette. It allows HRs to more easily evaluate a job candidate's soft skills in terms of professional appearance, behaviour and communication. When a company specifies that they give preference to IITTI Certificate holders, this company is advertising to the world that they care about good image and etiquette practice -- good for employer branding.
