Common Mistakes (and Fixes)

• Vague summaries: Use specific achievements and quantifiable results instead of generic statements like "responsible for sonar systems." For example, "calibrated and maintained sonar systems, reducing errors by ~15%."
• Overly dense paragraphs: Break down experience into clear, bullet-pointed accomplishments to improve ATS readability.
• Generic skills: Tailor skills to the role with precise tools or procedures, e.g., "Diagnosed hardware faults using Fluke multimeters" rather than just "troubleshooting."
• Decorative formatting: Avoid overly complex layouts, tables, or text boxes that ATS may not parse correctly.
• Lack of keywords: Incorporate synonyms and related terms like "underwater acoustics," "signal processing," and "marine electronics" to improve keyword matching.

ATS Tips You Shouldn't Skip

• Use relevant file names like Sonar_Technician_Resume_2025.pdf or .docx.
• Label sections clearly with standard headers (e.g., Skills, Experience, Certifications).
• Include keywords naturally throughout your resume, covering both technical and soft skills.
• Avoid images, graphics, or unusual fonts that can disrupt ATS parsing.
• Maintain consistent tense—use past tense for previous roles and present tense for current responsibilities.
• Save your resume in common formats preferred by ATS, typically PDF or Word documents.
• Check for proper spacing and avoid dense blocks of text or complex tables.
• Use standard section titles to ensure ATS recognizes each part of your resume correctly.

Following this guide will help you craft a clear, keyword-rich, ATS-optimized resume that highlights your skills and experience as a sonar technician, increasing your chances of landing interviews in 2025.
