Implementation Highlights

Intelligent Job Matching

// Example of the job matching algorithm
const findMatchingCandidates = async (jobId) => {
  const job = await Job.findById(jobId).lean();
  
  // Extract key skills and requirements
  const jobSkills = job.requiredSkills.map(skill => skill.toLowerCase());
  const jobExperience = job.experienceRequired;
  
  // Find candidates with matching skills
  const matchingCandidates = await User.find({
    role: 'jobseeker',
    'skills': { $in: jobSkills },
    'experience': { $gte: jobExperience }
  }).sort({ 
    // Sort by skill match percentage
    $expr: {
      $divide: [
        { $size: { $setIntersection: ['$skills', jobSkills] } },
        { $size: jobSkills }
      ]
    }
  }).limit(20);
  
  return matchingCandidates;
};
