According to the guidelines for effective cover letter construction, what depth should an applicant use when presenting key achievements under the Evidence section?

Deep-dive on only one or two compelling examples, explaining the result and the benefit mechanism for the new employer.

Effective construction mandates a strategic approach to presenting past performance, specifically within the 'Evidence' area. Instead of providing a long list of achievements, the instruction is to select one or two key examples that directly align with the most challenging requirements mentioned in the job description. The deep dive involves explaining not just what was achieved, but the concrete result of that achievement and, crucially, articulating how that same successful mechanism or process can be replicated to benefit the prospective employer. This level of focused detail offers more persuasive evidence than a superficial listing.
