A hiring manager's perspective on writing a data engineering CV for Europe and America is that it should demonstrate a good understanding of the role and what is expected, while also showcasing relevant skills and experience. A cover letter should be written to show motivation and why the candidate would be a good fit for the company, without being too generic. The CV itself should have a clear structure, with sections on bio, image, values, motivation, mission, skills, job experience, education, projects, and courses. Relevant skills should be listed first, and relevant technologies or tools mentioned in previous jobs can help personalize the list. Job experience should focus on achievements and takeaways, rather than just listing responsibilities. The hiring manager is looking for clear communication, better skills, and more applications, with opportunities depending on location and job market.
