Why is skill-level data (years/months of experience) not extracted from resumes?

Skill-level data, such as the number of years or months of experience with a specific skill, is only extracted by the parser if the skill is explicitly mentioned under structured sections like the ExperienceSection or similar well-organized areas in the resume. This typically includes:

• Experience Section: Where the candidate lists their job history, including roles, responsibilities, and years of experience.
  
  
• Project Section: Where specific skills are tied to projects, sometimes including the duration or the extent of experience with a skill.
  
  

Why Skill-Level Data Might Be Missing:

1. Lack of Structured Data:
   Many resumes do not include skill-level information (like experience in years or months) in the standard sections (Experience or Project). Without this explicit mention, the parser cannot infer or calculate the experience level, even if the skill is present elsewhere in the resume.
   
   
2. Variations in Resume Formatting:
   Resumes can have various formats and styles. Some resumes may list skills and experience in unstructured ways, which the parser may not be able to identify accurately. For example, if the skill is listed in a summary or other non-standard section without associated time details, the parser will not be able to extract the experience.
   
   
3. Experience Descriptions:
   If a skill is mentioned but there is no accompanying timeframe or context, the parser will treat it as a skill but will not associate it with any experience data (such as years/months).
   
   
4. Resume Variability:
   Every candidate has a unique way of structuring their resume. If they choose to mention skills without providing detailed context about the duration or the level of expertise, this data may be omitted in the parsed output.
