Sourcing - what it is and how it works in IT and recruitment
In today's world, where competition for talent is becoming increasingly fierce, the search for qualified specialists becomes a strategic task for any company.
That is why sourcing in IT is extremely important. Generally, the search for 'sourcing in recruitment is' quite popular. This topic deserves special attention.
What is sourcing
In this field, traditional recruitment methods are often not enough to find the right people - after all, the best candidates are not always actively looking for a job. That is why sourcing is gaining more and more importance - a process that allows finding potential employees even before they decide to change their workplace. This approach has become an integral part of the recruitment strategy in IT and other fields, helping companies not just fill vacancies, but create a quality talent pool.
Sourcing is the process of proactively searching, analyzing, and attracting potential candidates who may meet the company’s requirements, even if they are not actively looking for a job. Unlike standard recruiting, which focuses on working with those who have already applied, sourcing implies proactive activity: specialists search for talent on professional platforms, social networks, databases, forums, or even in programming communities.
The main goal of sourcing is to create a base of potential candidates who suit the company in terms of qualifications, experience, and cultural values. This is a strategic phase that helps reduce hiring time and improve the overall efficiency of recruitment.

In large IT companies, sourcers often work separately from recruiters. Their task is to find the right specialists, conduct an initial profile analysis, verify the relevance of experience, and then pass this information to the recruiter, who establishes contact and conducts further interview stages.
How sourcing differs from recruiting
Despite the fact that these terms are often used as synonyms, there is a significant difference between them.
Recruiting is the process aimed at attracting candidates who are already actively looking for a job. The recruiter publishes vacancies, communicates with candidates, conducts interviews, and negotiates terms with the employer.
Sourcing, on the other hand, is a preliminary stage that focuses on identifying potential candidates, often passive ones - those who do not submit resumes but may be interested in an attractive offer.
In other words, a sourcer is a ‘talent hunter’ who constantly monitors the job market. They must understand where the required specialists ‘live’ - in which communities, at which conferences, what tools they use.

Sourcing also involves analytical work: sourcers research competitors, compare candidate profiles, create targeted contact lists, and identify the most effective search sources. In recruiting, however, the main goal is to bring the process to hiring. Thus, sourcing and recruiting are two parts of one chain that mutually complement each other.
Main types of sourcing
There are several approaches to sourcing that differ in sources of search and tools:
- Online sourcing. The most common format, which includes searching for candidates in social networks (LinkedIn, GitHub, Facebook, X), on forums, in professional communities, or through special search queries (Boolean Search).
- Internal sourcing. Involves attracting specialists from within the company or its talent pool. This is an effective way to reduce costs and the adaptation period of new employees.
- Referral sourcing. Finding candidates through recommendations from current employees. In IT, this approach is especially valued, as it allows attracting verified specialists with a high level of trust.
- Offline sourcing. Used during conferences, meetups, hackathons, educational events, where one can meet potential employees in person.
- Automated sourcing. Involves the use of special tools and programs for searching and filtering candidates (for example, AmazingHiring, Hiretual, OctoHR). This significantly speeds up the process and allows collecting a contact base in a short time.
These types are the main ones, but not the only ones.
How the sourcing process is organized in a company
The organization of sourcing depends on the scale of the business and the number of open positions. In large IT companies, special sourcing departments are created that work closely with recruiters and HR analysts. First, a portrait of the ideal candidate is formed – their technical skills, experience, country of residence, level of English, etc. Then the sourcer develops a search strategy: determines where to look for such people and how to attract their attention.
In practice, the sourcer uses special search queries in Google or LinkedIn, analyzes profiles on GitHub or Stack Overflow, searches for contacts through professional chats and Slack communities. It is important to not only find a person but to understand what may motivate them to change jobs - interesting projects, salary, flexible hours, the company's reputation.

In small companies, sourcing is often performed by the recruiter themselves, combining both functions. In this case, it is essential to be able to effectively allocate time between searching for candidates and subsequent communication.
The impact of effective sourcing on candidate selection and employer branding
Quality sourcing significantly improves the speed and effectiveness of recruiting. With a well-thought-out strategy, the company gains access to a broader pool of candidates, including ‘passive’ specialists who do not respond to vacancies but can be the most valuable employees.
Moreover, sourcing affects the employer brand. When companies actively communicate with specialists, demonstrating transparency and respect, they create a positive impression in the market. People start to perceive it as an attractive employer, even if they are not currently looking for a job.
Sourcing also contributes to the development of an analytical culture in the HR department. The data obtained during the search for candidates helps to understand which skills are in demand, which companies are competitors, and how to better position their offers.
As a result, effective sourcing not only fills vacancies but also creates a strong talent foundation for further business development, ensuring its stability and competitiveness in the labor market.
Examples of successful sourcing in well-known companies
Many leading companies in the IT sphere have proven the effectiveness of sourcing as a key talent acquisition tool. For example, Google actively utilizes the search for passive candidates through LinkedIn, GitHub, and its internal databases. The company does not limit itself to standard job postings but forms a pool of specialists for future projects, allowing it to quickly close even very specific positions. Thanks to this, Google always has access to highly qualified engineers who meet the modern technological market’s demands.
Microsoft applies a similar strategy. The company’s sourcers actively use professional communities, forums, and conferences to find specialists in narrow technological niches. Importantly, Microsoft pays great attention to building relationships with candidates, even if they are not ready to immediately accept an offer. This approach allows forming long-term partnerships and ensuring the company has a constant flow of talented specialists.

Another example is Facebook (Meta). Here, sourcing combines traditional methods with modern technological tools. The company uses AI platforms to analyze resumes, social media profiles, and databases of participants from technical communities. This allows quickly finding passive candidates who possess unique skills and offering them personalized job vacancies.
The success of sourcing often depends not only on technology but also on the corporate culture of the company. Organizations that actively publish case studies, success stories of employees, and openly communicate their values receive more feedback from potential candidates. Thus, effective sourcing creates synergy between talent acquisition and the formation of a positive employer brand.
Mistakes during sourcing
Despite its high potential, sourcing has its pitfalls that can significantly reduce the process's effectiveness. One of the most common mistakes is a lack of understanding of the candidate's profile. If a sourcer has not defined clear requirements for experience, skills, place of residence, or level of English, the search becomes chaotic and leads to a large number of irrelevant contacts.
Another mistake is ignoring passive candidates or insufficient work with them. Some companies confine themselves to only active resumes, not considering that most qualified specialists do not openly search for jobs. Losing this audience significantly narrows the talent pool and reduces the chances of finding a truly valuable employee.
A common problem is a lack of communication with recruiters and HR analysts. If the sourcer and recruiter do not work as a single team, it is challenging to synchronize information about candidates, hiring timelines, and expectations from the vacancy. This leads to duplication of work and delays in the recruitment process.

Another mistake is excessive automation without a personal approach. Using AI and search platforms is useful, but relying entirely on technology without analyzing the candidate's profile, checking motivation, and preparing personalized offers - is a risk of losing valuable specialists.
Finally, it is essential to avoid an opaque or overly aggressive approach to candidates. Poor contact, unwanted frequency of messages, or uninteresting offers can negatively affect the company’s reputation and create rejection.
Proper sourcing requires a clear strategy, analysis, and attention to detail, and avoiding these mistakes significantly enhances the quality of recruitment and positively impacts the employer brand.
