No, you are not walking into their building for your interview. Instead, you are inviting each other into your personal space. The interviewer may conduct the meeting in their office where you will see bits of “them” and what they are like as a person and professional.
You are also welcoming them into your personal space. Be mindful of what you are sharing and how to show off the very best of you. Many of us do not have fancy home offices and are having these interviews in our living rooms, bedrooms, or on the kitchen table! There is nothing wrong with that. In fact, if done correctly, it can really showcase certain sides of you they may not ever learn about that could tip the scale in your favor.
For instance, show that you keep a clean “workspace.” Tidy up, pick up your laundry, make your bed, put the dishes away. Reduce distractions that could make it difficult for them to focus and hear what you are saying. While we all love The Goonies, maybe keep that movie poster out of the camera’s line of sight.
Your appearance matters too. While we all are adapting to virtual interviews and remote work, we need to maintain a level of professionalism. If nothing else, being more professional than other interviewees could set you apart! Style your hair, dress professionally (maybe not your “Sunday best” but close), and remember first impressions really do matter.
