When recruiting, it's important to focus on the data that aligns with your goals, challenges, and opportunities. Some of the most common and useful data sources include Applicant Tracking System (ATS) data, which contains information on candidates such as resumes, applications, assessments, and feedback. This can be used to track your pipeline, identify bottlenecks, and optimize your hiring funnel. Recruitment marketing data includes information on your employer brand such as website traffic, social media engagement, and online reviews. This can be used to measure your reputation, attract more qualified candidates, and optimize your campaigns. Lastly, employee data contains information on current and former employees such as their performance, satisfaction, and turnover. This can help you predict the success and retention of your hires, improve your employee experience, and identify areas for improvement.
