Discover the Surprising Differences Between Big Data and Small Data in Recruitment and How They Impact Your Hiring Strategy.
Recruitment process has evolved over the years, and with the advent of technology, it has become more data-driven. The use of data in recruitment has given rise to two types of data – Big Data and Small Data. In this article, we will explore the differences between Big Data and Small Data in recruitment and their impact on the recruitment process.
Big Data in Recruitment
Big Data refers to the large volume of data that is generated from various sources such as social media, job portals, and other online platforms. The use of Big Data in recruitment has become increasingly popular in recent years. Here’s how Big Data impacts the recruitment process:
| Step | Action | Novel Insight | Risk Factors |
|---|---|---|---|
| Talent Acquisition | Collecting data from various sources such as social media, job portals, and other online platforms. | Big Data provides a vast pool of candidates to choose from, which increases the chances of finding the right candidate. | The use of Big Data can lead to information overload, making it difficult to filter out irrelevant data. |
| Data Mining | Analyzing the data to identify patterns and trends. | Big Data helps in identifying patterns and trends that can be used to predict future hiring needs. | The accuracy of the predictions depends on the quality of the data. |
| Predictive Analytics | Using the data to make predictions about future hiring needs. | Predictive analytics can help in identifying the best candidates for a particular job. | The predictions may not always be accurate, leading to wrong hiring decisions. |
| Candidate Selection | Using the data to select the best candidate for the job. | Big Data helps in identifying the best candidate for the job based on their skills, experience, and other factors. | The use of Big Data can lead to bias in the selection process. |
Small Data in Recruitment
Small Data refers to the data that is collected from a limited number of sources such as resumes, job applications, and interviews. Here’s how Small Data impacts the recruitment process:
| Step | Action | Novel Insight | Risk Factors |
|---|---|---|---|
| Talent Acquisition | Collecting data from resumes, job applications, and interviews. | Small Data provides a limited pool of candidates to choose from, which may not always result in finding the right candidate. | The use of Small Data may result in missing out on potential candidates who may not have applied through traditional channels. |
| Candidate Selection | Using the data to select the best candidate for the job. | Small Data helps in selecting the best candidate based on their skills, experience, and other factors. | The use of Small Data may result in missing out on important information about the candidate that may not be available through traditional channels. |
Conclusion
Both Big Data and Small Data have their advantages and disadvantages when it comes to recruitment. While Big Data provides a vast pool of candidates to choose from, it can also lead to information overload and bias in the selection process. On the other hand, Small Data provides a limited pool of candidates to choose from, which may result in missing out on potential candidates. Therefore, it is important to strike a balance between the two and use them in conjunction with each other to make informed hiring decisions.

What is the Recruitment Process and How Does Big Data Impact It?
| Step | Action | Novel Insight | Risk Factors |
|---|---|---|---|
| 1 | Resume screening | ATS is used to filter resumes based on keywords and qualifications | ATS may eliminate qualified candidates due to lack of specific keywords |
| 2 | Candidate selection | Big data analytics is used to analyze candidate data and predict job performance | Predictive modeling may not always accurately predict job performance |
| 3 | Interview process | Pre-employment assessments are used to evaluate candidate skills and personality traits | Pre-employment assessments may not accurately reflect a candidate’s potential job performance |
| 4 | Onboarding | Talent acquisition metrics are used to measure the effectiveness of the recruitment process | Poor onboarding may lead to high turnover rates |
| 5 | Diversity and inclusion initiatives | Employer branding strategies are used to attract diverse candidates and promote a positive company culture | Lack of diversity and inclusion may lead to negative company reputation |
| 6 | Recruitment marketing campaigns | Social media recruiting is used to reach a wider audience and attract passive candidates | Overreliance on social media may limit the pool of qualified candidates |
| 7 | Talent pipeline development | Companies focus on building relationships with potential candidates for future job openings | Lack of talent pipeline development may lead to difficulty filling open positions |
Overall, big data has revolutionized the recruitment process by providing insights into candidate data and predicting job performance. However, there are risks associated with relying solely on big data, such as eliminating qualified candidates due to lack of specific keywords or inaccurate predictive modeling. It is important for companies to balance the use of big data with traditional recruitment methods and focus on building a diverse and inclusive workforce through employer branding strategies and talent pipeline development.
The Role of HR Analytics in Candidate Selection: Is Big Data Always Better?

Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Big data is always better than small data in recruitment. | The size of the data does not determine its effectiveness in recruitment. Both big and small data can be useful depending on the specific needs and goals of the organization. |
| Small businesses do not need to use big data for recruitment. | Even small businesses can benefit from using big data in their recruitment processes, as it allows them to make more informed decisions about candidates and improve their hiring outcomes. However, they may also find that smaller datasets are sufficient for their needs. |
| Big data eliminates human bias in hiring decisions. | While big data can help reduce some forms of bias by providing objective metrics and insights, it is still subject to biases inherent in the algorithms used to analyze the data or the way that it was collected or processed initially. Human oversight is still necessary to ensure fair and equitable hiring practices. |
| Small datasets cannot provide meaningful insights into candidate performance or potential fit with a company culture. | Smaller datasets can still offer valuable information about candidate qualifications, skills, experience, personality traits, etc., which can inform hiring decisions just as effectively as larger datasets when analyzed correctly. |
| Using only one type of dataset (big/small) will guarantee successful hires every time. | No single approach guarantees perfect hires every time; rather a combination of different types of datasets (e.g., resumes/CVs, interviews/assessments) should be used together with both large and small sets where appropriate for optimal results. |
