Prior to the interview day, conduct comprehensive research on the company, job description, and staff, and consider connecting with them on LinkedIn. On the day of the interview, prioritize punctuality by arriving 20 minutes before the scheduled time, and dress appropriately in formal-casual attire. When offered a beverage, confidently choose between coffee or water. Minimize distractions by removing items like pens or phones, and bring printed copies of your resume and relevant projects.
