An applicant tracking system (ATS) is a software application that enables the electronic handling of recruitment and hiring needs. It helps organizations manage resumes, job postings, and candidate communications, streamlining the hiring process and reducing manual labor. The main goal of an ATS is to improve the efficiency and effectiveness of a company's hiring process.

To get an applicant tracking system (ATS) to filter you as a candidate, it's important to use keywords relevant to the job you're applying for. Here are some steps you can follow:

1. Review the job posting carefully and make a list of relevant keywords such as job title, required skills, responsibilities, etc.
2. Use those keywords in your resume and cover letter, making sure to sprinkle them throughout, including in your summary, skills, and work experience sections.
3. Try to match the language used in the job posting as closely as possible.
4. Use bullet points to make your resume easy to scan, and avoid using graphics, images, or tables, as these can make your resume difficult for an ATS to process.
5. Avoid using fancy fonts or formatting, as the ATS may not be able to read it properly.

By using these techniques, you can increase the chances of your resume being filtered positively by an applicant tracking system, and making it to the hands of a hiring manager for review.
