In a recent LinkedIn post, Eric Sim explores practical strategies for professionals to significantly enhance their presence during online interviews and presentations. Responding to a question from a London Business School alumnus about his presentation setup, Sim detailed his method for writing on an iPad and overlaying it onto his video feed, a technique he employs to explain complex ideas visually while maintaining direct engagement with his audience.
The Power of Visual Engagement in Online Communication
Sim’s approach addresses a common challenge in virtual professional interactions: how to convey information effectively and maintain a polished appearance. He explains his setup, which involves using an iPad with an Apple Pencil for notes and diagrams. This visual content, along with his DSLR camera feed, is then processed through a live production switcher. This device seamlessly combines the two sources, allowing them to be transmitted directly to platforms like Zoom.
“I write on my iPad with an Apple Pencil, then feed both my iPad and DSLR camera into a live production switcher (the device left of my laptop). It combines the two sources and sends it out to Zoom.”
This method, as Sim points out, offers several advantages. It enables him to “explain ideas through handwritten notes and diagrams while keeping my face in full view.” Crucially, it also eliminates the need for screen sharing, a feature often disabled in online interviews, thereby maintaining a more consistent and professional presentation flow.
Investing in First Impressions for Career Success
Beyond the technical setup, Eric Sim emphasizes the disproportionate impact of initial moments in high-stakes professional scenarios, particularly job interviews. He draws a parallel between the extensive time spent on education and the brief window of opportunity in a first interview.
The Interview Window
Sim highlights the critical nature of the first five minutes of an interview, stating:
“Most of us spent at least 18 years studying, yet our career is decided in the first five minutes of a job interview.”
He advocates for a modest investment in production quality—lighting, audio, and visual presentation—arguing that these elements can significantly influence an interviewer’s perception. According to Sim, a strong initial impression can lead interviewers to actively seek out and confirm positive attributes, reinforcing their favorable view.
Strategic Investment in Video Presence
Sim poses a direct question to his audience, prompting reflection on the value of investing in their online presentation:
“Are you willing to invest a little time, effort and money in how you look and sound on video calls to increase your chances of landing a good job or attracting new business?”
He suggests that such an investment is not merely about aesthetics but a strategic move to improve professional outcomes, whether securing a desired job or attracting new clients. Sim concludes by thanking Mhorag Doig for the invitation to speak with her alumni and students, noting their engagement and the positive experience.
