Sourcing Candidates: How to Find Talent Before Applying

Why sourcing is the most important competence in recruitment

The biggest mistake recruiting teams make is waiting for talent to come to them. You post an ad, wait for applications, filter CVs - this reactive model seems logical, but it ignores a crucial reality of the labor market: 70% of qualified professionals are passive candidates. They are not actively looking for a job, they are not responding to ads and they are not browsing recruitment platforms. But that doesn't mean they wouldn't be interested in the right opportunity.

Sourcing means identifying, contacting and attracting these candidates before they apply - or even before they know that there is an open position that would suit them. It's the difference between waiting for the fish to come to you and going where the fish are. Companies that practice active sourcing reduce time-to-hire by 30-40% and have a significantly better retention rate, because they hire people who really fit the role, not just people who urgently needed a job.

In Romania, this reality is even more acute. In the IT market, for example, the unemployment rate is below 2%, which means that almost all competent professionals are already employed. If you rely exclusively on job ads, you are competing for the same 30% of the market as all other companies. If you practice sourcing, you have access to the entire market.

The 6 main sourcing channels

Effective sourcing means being present on several channels simultaneously and adapting the approach according to the profile of the candidate you are looking for. Here are the most productive channels and how to use them strategically:

1. LinkedIn - regele sourcing-ului profesional.LinkedIn remains the number 1 platform for identifying passive candidates. The advanced search allows filtering by location, experience, current company, skills and even education level. InMails have a response rate of 18-25% when they are personalized - 3-4 times higher than cold emails. The key is not to send generic messages ("We have a position that might interest you"), but to mention exactly what attracted you from the candidate's profile ("I noticed that you led the migration to microservices at Company X - this is exactly the type of experience we were looking for").

2. Internal database of candidates.This is, paradoxically, the most underestimated source of talent. Every candidate who has ever applied to your company, every CV received, every person who reached the final stage but was not selected - they all represent potential future hires. The problem is that, without an ATS, these data are lost in email folders or forgotten Excel files.

3. Referrals from employees.Your employees know professionals in the field. A well-structured referral program can generate 25-40% of a company's hires, with a cost per hire 2-3 times lower than other channels. In Treegarden, the source of each candidate is automatically recorded. When an employee recommends someone, the recruiter marks the source as "Referral" and can track the candidate's progress from recommendation to employment - essential data to evaluate the effectiveness of the program.

4. Professional communities and events.Technical meetups, industry conferences, professional groups on Facebook or Discord, specialized forums - all are sources of high-quality passive candidates. Active participation in these communities builds visibility and trust, and when you advertise a position, you already have a relationship with potential candidates.

5. Partnerships with universities.For entry-level positions and internship programs, the relationship with universities is fundamental. The presence at job fairs, mentorships, workshops and practice programs creates a constant flow of young talents. Treegarden allows the creation of dedicated pipelines for candidates from university programs, with adapted stages (eg "Practical Application", "Academic Interview", "Project Evaluation").

6. Social media and employer branding.The content your company publishes on LinkedIn, Instagram or Twitter builds an image that attracts long-term passive candidates. Articles about company culture, employee testimonials, posts about projects and technologies - all contribute to an employer brand that makes candidates respond when you contact them. The Treegarden career page is part of this strategy: an attractive site with its own brand, which presents the jobs, the team and the company's values.

Building a talent pipeline: from contact to hire

Sourcing is not an event, but an ongoing process. The best way to manage it is by building a talent pipeline - a structured list of potential candidates for roles you know will be open in the future.

Pasul 1: Identifica rolurile recurente.Analyze the employment history. If every quarter you hire 2-3 backend developers, it means that you must always have an active pipeline for this position. Don't wait for the role to open - start sourcing early.

Step 2: Add candidates to Treegarden.Any interesting professional you discover on LinkedIn, at an event or through a recommendation can be added to the Candidate Database. Upload your CV (if you have one), add notes about observed skills and relevant tags (for example: "Python", "Senior", "Available Q2 2026").

Pasul 3: Mentine relatia calda.A candidate contacted today may not be available now, but could be in 6 months. Periodically send them relevant content: blog articles, invitations to events, news about interesting company projects. When the role opens, you don't start from scratch.

Step 4: Activate the pipeline when the role opens.When a new position appears, the first thing you do in Treegarden is to search the existing database. Before publishing the ad, you already have a list of pre-qualified candidates that you can contact directly. This can reduce the time-to-hire by 2-3 weeks.

Sourcing: How to measure the ROI of each sourcing channel

Not all sourcing channels are equal. A channel that generates 100 applications but no employment is more expensive than one that generates 10 applications and 2 employments. Therefore, tracking the source of each candidate is critical for optimizing the budget and recruitment effort.

Treegarden automatically records the source of each candidate. When someone applies through the career page, the source is marked as "Career Page". When it comes through eJobs, BestJobs or LinkedIn, the source reflects the respective platform. For manually added candidates (referrals, direct sourcing), the recruiter selects the appropriate source.

With this data, you can generate reports that answer essential questions:

• Which channel generates the most qualified candidates?Not just volume, but candidates with an AI Match Score above a certain threshold.
• Which channel has the best conversion rate?How many candidates come through each channel, how many reach the interview and how many are hired?
• What is the cost per hire on each channel?LinkedIn InMail costs money, eJobs has a monthly subscription, referrals have bonuses - which investment brings the best return?
• How does the effectiveness of the channels evolve over time?Maybe eJobs was working well a year ago, but the performance decreased, while the referrals increased constantly.

How to write sourcing messages that get a response

Sourcing does not stop at identifying candidates. The most difficult part is to convince them to answer. Passive candidates receive an average of 3-5 recruitment messages per week on LinkedIn. If your message looks like a generic copy-paste, it will be ignored. Here are the principles that make the difference:

Personalizeaza primul rand.Don't start with "We have an interesting opportunity". Start with something specific about the candidate: "I read your article on optimizing NoSQL databases and was impressed by the approach you described" or "I noticed you contributed to the open-source X project - we were looking for exactly this level of expertise."

Be specific about the opportunity.Not "a senior developer position in an innovative company". Ci: "We are looking for a Tech Lead for a team of 8 developers building a SaaS recruitment platform. The salary is between 12,000-16,000 RON net, we work hybrid (3 days office + 2 remote) and we have stock options."

Explain why you wrote to him/her.The candidate must understand that he is not one of a thousand messages sent in the mass: "Your 4 years of experience with Kubernetes at CompanyY is exactly what we need for the scaling challenges we have."

It includes a simple call-to-action.It does not ask for a CV or a formal application. He proposes a 15-minute conversation, without commitment: "Are you available for a short call next week? I want to tell you more and see if you would be interested."

Respect a "no" with grace.If the candidate refuses, thank him and keep the relationship: "I understand perfectly. If the situation changes in the future, don't hesitate to contact me." In Treegarden, you can add a note on the candidate's profile: "Contacted Jan 2026, not interested now, to be contacted again in Q3 2026."

The Treegarden database as a sourcing tool

As your company recruits, the Treegarden database grows organically. After a year of use, a medium-sized company accumulates between 500 and 5,000 candidate profiles - each with CV, grades, AI score and full history of interactions. This database is the most valuable sourcing asset you own.

The functionality ofCV Content Searchmakes the critical difference. Unlike other ATSs that allow searching only by structured fields (name, email, position), Treegarden searches in the actual content of CVs. If you need someone with experience in "SAP HANA", search for this exact phrase and you will get all the candidates who mentioned it in their CV - even if they applied for completely different roles.

The practical scenario looks like this: your sales department opens a position of Account Manager with experience in SaaS. Before publishing the ad, open the Candidate Database and search for "account management" + "SaaS". Treegarden returns 12 candidates from the last 18 months who have these skills in their CV. Three of them applied for a Customer Success role 8 months ago and reached the final stage. You contact them, you present them with the new opportunity and you already have a shortlist before the announcement is public.

This flow transforms recruitment from a reactive process to a proactive one. You no longer wait for applications - you anticipate them. You no longer start from scratch for each role - you build on existing relationships. And you never lose a good candidate just because it wasn't the right time at the first interaction.

How to build a complete sourcing strategy

Sourcing is not an activity you do when you urgently need a candidate. It is a constant discipline that, practiced correctly, removes the urgency from recruitment. Here is a concrete action plan:

1. Saptamanal:Spend 2-3 hours on LinkedIn identifying candidates for the roles you anticipate in the next quarter. Add them to Treegarden with notes and tags.
2. Lunar:Analyze the report of sources from Treegarden. Adjust the investment on each channel according to real performance.
3. For each new role:Before publishing the ad, search the existing database. Contact relevant candidates directly.
4. Trimestrial:Review the referral program. Communicate open positions and incentives to employees. Check the referral conversion rate.
5. Continuu:Publish employer branding content on social media. Participate in professional events. Build relationships, not just pipelines.

Sourcing is a long-term investment. The results do not appear overnight, but after 6 months of constant practice, you will notice a fundamental transformation: roles are filled faster, candidates are more qualified, costs decrease and the HR team spends less time on reactive screening and more on strategic relationships with talents.

With Treegarden, you have all the tools you need: a database with advanced CV search, automatic source tracking, flexible pipelines, AI Match Score for quick assessment and a career page that builds your employer brand. Transform your recruitment from reactive to proactive - the results will surprise you.
