Varun's response is inappropriate and does not address the question regarding a successful SEO or digital marketing campaign. Instead, it includes an unrelated and unprofessional comment, which detracts significantly from his credibility as a candidate. In contrast, the benchmark response provides a clear and structured overview of a successful digital marketing campaign, detailing the strategies employed and the measurable outcomes achieved. It highlights specific actions taken, such as conducting an SEO audit, optimizing content, and improving the backlink profile, along with quantifiable results that demonstrate the campaign's success. Varun needs to focus on providing relevant and professional responses that directly address the interview questions.
