Varun's response is inappropriate and unprofessional, as it does not address the question regarding his experience with SEO or digital marketing campaigns. Instead, he expresses an unrelated sentiment, which detracts from his credibility as a candidate. In contrast, the benchmark response effectively outlines a successful digital marketing campaign, detailing the strategies employed and the measurable outcomes achieved. It provides a clear narrative of the campaign's objectives, actions taken, and results, demonstrating a strong understanding of how digital marketing can enhance e-commerce traffic and sales. To improve, Varun must focus on providing relevant and professional responses that directly address the questions asked, showcasing his expertise in the field.
