The quality of your resume and cover letter are a reflection of the quality that you provide in your work. In these 2 documents, we will highlight your strengths, achievements, as well as offerings. The documents will be selling you as a service with a business proposition and therefore will tailor to the needs of the companies you are looking at. Some of the most common pitfalls I see are the tendency of people to highlight personal achievements rather than contributions and their impact on others. I will also optimize them with keywords to ensure you get past automation filters.
