A common misconception about IT hiring is that technical skills are sufficient to get hired. They are necessary but not sufficient. The mechanism that consistently produces the best outcomes — shorter search times, better role fit, higher starting salaries — is professional networking, specifically the kind that produces referrals.
This is not an argument for schmoozing or career fairs. It is an argument for building a small number of genuine professional relationships and maintaining them over time.
The Data on Referrals
The evidence for referral-based hiring is strong and consistent across studies:
"Weak ties are your most underrated career asset. Your close network shares your opportunities. It is the people you know less well — former classmates, conference contacts, online community members — who have access to different job markets and can introduce you to them." — Mark Granovetter, sociologist at Stanford University and author of "The Strength of Weak Ties" (American Journal of Sociology, 1973), the foundational research on social networks and information flow
- LinkedIn reports that 70 percent of jobs are filled through networking, many before a public posting exists
- Jobvite's annual survey consistently finds referred candidates are hired at 3-4 times the rate of non-referred applicants
- Employee referrals account for approximately 30-50 percent of all hires at technology companies, despite being a small fraction of applicants
- The 2023 Greenhouse Hiring Benchmark found referred candidates spend 55 percent less time in the hiring process
Companies pay referral bonuses of $5,000-$25,000 specifically because the data justifies it. A referred candidate who is vouched for by a current employee starts the hiring process with a significant credibility advantage that a cold application cannot replicate.
The sociological basis for this is Mark Granovetter's research on "the strength of weak ties." Your close connections largely share your knowledge and network. It is weak ties — people you know somewhat but not closely — who provide access to new information, new opportunities, and new introductions.
Two Types of IT Networking
Type 1: Relationship Building (Long Cycle)
Long-cycle networking produces results over months or years. It involves building genuine professional relationships with peers, former colleagues, managers, professors, bootcamp cohorts, and community members. These relationships are low-pressure and mutual — you help them as much as they help you.
Activities that build long-cycle relationships:
- Contributing to open-source projects and engaging with maintainers
- Participating in community Slack groups (AWS Community, CNCF Slack, HashiCorp Discuss)
- Attending local tech meetups or user groups (ISSA chapters, AWS User Groups, Docker meetups)
- Being active in subreddits like r/sysadmin, r/networking, r/devops by contributing useful answers
- Maintaining contact with former colleagues through periodic check-ins
Long-cycle networking is what produces the "I know someone who is hiring" call you receive without asking for it.
Type 2: Targeted Relationship Building (Short Cycle)
Short-cycle networking is what you do during an active job search. You identify specific companies you want to work for and build relationships with people inside those companies, specifically to learn about opportunities and potentially get referred.
This is not manipulative if done honestly. People expect to be asked for referrals during job searches. The key is to provide value in the relationship before making an ask, and to make the ask direct and specific when you do.
How to Get a Referral at a Target Company
Step 1: Identify 15-20 target companies and list them in a spreadsheet.
Step 2: Search LinkedIn for connections who work at each company, even second or third-degree connections. Look for people with similar roles to what you are targeting.
Step 3: Request a 20-minute informational interview. The goal is to learn about the team, culture, and what the role actually involves day-to-day — not to ask for a job.
An effective informational interview request:
"Hi [Name], I am a cloud engineer with 3 years of AWS experience looking to move into a product-focused environment. I noticed [Company] has been doing interesting work in [specific area]. Would you have 20 minutes to share what the cloud infrastructure team looks like there? I am not asking you to do anything — just a quick conversation would be incredibly helpful."
Step 4: During the call, ask good questions about the team, the stack, the challenges they are working on. Do not make it about job searching. Let them volunteer that information.
Step 5: After the call, send a thank-you message. Stay in touch. If there is a role that opens up and you are interested, it is entirely appropriate to ask: "I noticed a Cloud Engineer role just opened on your team. Would you be comfortable referring me? I understand if not."
Most people who have had a positive informational conversation will say yes to a referral request if they believe you are qualified.
Warm vs. Cold Outreach
Not all outreach is equal:
| Outreach Type | Relationship Level | Expected Response Rate |
|---|---|---|
| Former colleague refers you | Strong tie | Near certain |
| Mutual connection introduction | Weak tie | 60-80% |
| LinkedIn with common group/connection | Semi-warm | 30-50% |
| Cold LinkedIn InMail | No relationship | 15-25% |
| Job board application | None | 2-8% |
The higher you can start in this table, the better. Always look for a mutual connection who can facilitate an introduction before sending cold outreach.
Specific Networking Channels for IT Roles
Community Slack Groups and Discord Servers
Technical communities have active Slack and Discord servers where professionals discuss real problems and share career opportunities. These are not primarily job boards — they are professional communities. But they naturally produce job leads because people share openings with the community before posting them publicly.
Active communities by specialty:
- Cloud: AWS Community Builders program, Google Cloud Champion Innovators
- DevOps/Platform: CNCF Slack (75,000+ members), HashiCorp Discuss, DevOps Slack
- Security: TrustedSec Community, BlueTeam Labs, ISSA local chapters
- Networking: Network to Code Slack, Cisco DevNet community
- General IT: Spiceworks community, r/sysadmin, MacAdmins Slack
Participate for several weeks before making any career-related requests. Establish a presence by answering questions or sharing useful information first.
Local Meetups
Despite remote work trends, local meetups remain effective because:
- Geographic proximity is a real filter for many employers, even for hybrid roles
- In-person conversations build trust faster than online interactions
- Local tech scenes often have tight networks where knowing one person leads to knowing many
Find local meetups at Meetup.com, Eventbrite, or through your city's tech community. ISSA (Information Systems Security Association) chapters, AWS User Groups, and DevOps Days events are reliable starting points.
Former Colleagues and Managers
The most underutilized networking channel is your existing professional history. Former managers who thought highly of your work will frequently advocate for you at their current companies. Former colleagues who have moved to interesting companies are warm contacts who can facilitate introductions.
A quarterly practice: look at your contact list and reach out to 3-4 people you have not spoken with recently. Not to ask for anything — just to maintain the relationship. This is what makes "I have someone you should talk to" calls possible.
Alumni Networks
University alumni networks and bootcamp alumni groups are underused networking resources. Shared background creates an instant warm introduction context. Many alumni are willing to have informational conversations with recent graduates or people who attended the same program.
Tracking Networking Activity
Networking without tracking is like fishing without knowing where the fish are. Keep a CRM-style spreadsheet or use a free tool like Notion or Airtable to track:
- Name and company
- How you know them
- Date of last contact
- Conversation notes
- Next action and date
Review this monthly. The people you want to stay in contact with should not go more than 3-4 months without a touchpoint.
What Not to Do
Do not ask for a job in the first message. Start with an informational request or a genuine question about their work. The referral or opportunity comes after a relationship exists.
Do not only reach out when you need something. Periodic contact for genuine reasons (sharing an article, congratulating on a promotion, asking for advice on a technical problem) keeps the relationship alive without a transactional feel.
Do not neglect your existing network. Most people focus their networking energy on new contacts while letting existing relationships decay. Your warmest network is the one you already have.
Do not mistake LinkedIn activity for networking. Liking posts and accepting connections is not relationship building. Conversations are.

Frequently Asked Questions
How much better are referrals than cold job applications?
Significantly better. Referred candidates are hired at 3-4 times the rate of cold applicants. LinkedIn data shows 70 percent of jobs are filled through networking, many before a public posting exists. Companies pay \(5,000-\)25,000 in referral bonuses because referred hires are consistently higher quality and faster to onboard.
How do I ask someone for a referral without it being awkward?
Have a conversation first. Request a 20-minute informational interview, ask genuine questions about their team and role, and build a brief relationship. After a positive conversation, it is entirely appropriate to say: 'I noticed a Cloud Engineer role just opened on your team. Would you be comfortable referring me?' Most people who had a good conversation will say yes if they think you are qualified.
What IT community groups are best for networking?
By specialty: Cloud professionals should join CNCF Slack, AWS Community, and DevOps Slack. Security professionals benefit from ISSA local chapters and BlueTeam Labs. Network engineers are active in Network to Code Slack and Cisco DevNet. General IT has r/sysadmin and Spiceworks. Participate by contributing answers before making any career-related requests.
Does local networking still matter for IT roles when most jobs are remote?
Yes. Geographic proximity is still a real filter for many employers even in hybrid or partially remote roles. In-person conversations build trust faster than online interactions. Local tech scenes often have tight networks where one introduction leads to many. Local meetups, ISSA chapters, and AWS User Groups remain effective even in a remote-first era.
How often should I follow up with my professional network?
Keep a contact log and aim for a touchpoint every 3-4 months with your most valuable contacts. These do not need to be job-related — sharing a useful article, congratulating someone on a promotion, or asking a genuine technical question all count. Relationships that go dormant for over a year become cold and require more effort to re-activate.
