Your Next Job Lead May Come from Someone You Barely Know

Your closest contacts may hear the same news

Imagine looking for an operations role. Your closest colleagues all work in the same team and follow the same employers. A former course partner now works in a different sector and knows how that sector names similar work. One conversation could broaden your search even if that person has no vacancy to offer.

This is a fictional example, not a reported hiring success. It illustrates why the information available through a relationship can matter as much as the closeness of the relationship.

What a large experiment found

A 2022 Science paper by Karthik Rajkumar and co-authors analysed randomized experiments on LinkedIn's People You May Know recommendations. Different recommendations changed the mix of stronger and weaker connections available to users. The research covered roughly 20 million people over five years.

MIT's account reports that weaker ties helped job mobility on average, but the relationship depended on how tie strength was measured. When measured through mutual connections, moderately weak ties were especially useful. This is not evidence that collecting the largest possible number of strangers is the best strategy.

The intervention changed connection recommendations. It did not test a specific cold-message script, a daily outreach quota or the promise of a referral. Those claims would go beyond the experiment.

Why the result is more interesting than 'network more'

The authors' Stanford research summary distinguishes two measures: mutual contacts and interaction intensity. They did not produce identical patterns. It also reports differences between industries: weak ties were more useful for mobility in more digital industries, while stronger ties mattered more in less digital ones.

A useful interpretation is to look for relevant information beyond the circle you already hear from. That still leaves room for close relationships, trust and specialist experience. The study does not make existing colleagues less valuable.

Both university sources describe the same research. Their agreement is not independent replication, and observations from the 2015–2019 experiments should not be presented as a guarantee about today's platform algorithm.

Choose a question before choosing a contact

Our practical recommendation is to identify one missing piece of information in your search. Perhaps you do not know which job titles describe your skills, what evidence a portfolio should include or whether a role usually requires a particular qualification.

Then think of someone with a genuine connection to that question: a former classmate, a previous project collaborator or a person whose public work you have read carefully. You are looking for a relevant perspective, not treating every connection as a potential recruiter.

Make the request small enough to answer comfortably. Asking which skill an entry-level analyst uses most often is more specific than asking someone to explain an entire career path or find you a job.

An original message you can adapt honestly

For example: 'Hi Maya, we worked together on the course project last year. I am exploring junior operations roles and noticed that you moved into that area. In your experience, which task should a beginner be able to demonstrate clearly? A short reply would help, but no pressure if you are busy.'

Use that structure only when the connection and context are real. If you have never met, say what public work led you to the person instead of implying a relationship. Avoid sending the same message to a large list.

If someone offers guidance, thank them and use it. Ask before treating an introduction as a recommendation or using their name in an application. A conversation is not an endorsement, and a referral is not a hiring decision.

Measure what you learned, not just who replied

Keep a short note after a useful conversation: the role title you discovered, the skill you need to demonstrate, the employer question you can now answer or the assumption you corrected. This is our suggested learning exercise, not a validated job-search formula.

Continue checking official vacancies and applying where you meet the real requirements. Networking can inform that process; it does not replace eligibility, relevant skills or an employer's selection process.
