interview processes and what to wear
Telephone interviews assess clarity motivation and basic fit. Choose a quiet space smile as you speak and have notes ready. Wear smart casual to feel professional.
Video interviews via Zoom or similar platforms test communication presence and technical understanding. Check technology lighting and background. Wear business smart attire as you would for an office meeting.
In person interviews allow deeper connection and site understanding. Arrive early bring copies of your CV and dress business smart. In engineering environments a suit with practical shoes is appropriate.
Panel interviews involve multiple stakeholders. Maintain eye contact with all panellists and answer clearly. Professional business attire shows respect.
