Impact on Job Seekers

- Relevant experience must be clearly highlighted
Key Insight
In modern hiring, resumes must be designed for both machines (ATS) and humans (recruiters).

What Influences First Impression

If the first impression is weak, the resume may not be read further in detail.

Bias can affect fairness and lead to subjective hiring decisions.

Key Insight
