Your Team's Hidden Superpower? Their Weekend Hobbies.

We have seen the same initiative play out differently at different companies: making employee interests visible so people can find each other across departments. At some, participation spread in weeks. At others, it stalled and quietly died. Same idea. Opposite outcomes. The difference was never the tool or the policy. It was how they introduced it.

This article is about the practical mechanics of making interest-based connection work inside a company. What follows is the sequence of decisions that separates the version that sticks from the version that becomes another dead HR initiative.

Start With What You Can See

Most companies already have informal interest groups. A few runners who train together. A Slack channel for cooking. A cluster of board game people who eat lunch together on Fridays.

But these groups are invisible to the rest of the organization. They form through proximity, which means they are usually people from the same team or the same floor. They do not cross department lines.

That matters because cross-department trust is the expensive thing to build. People within the same team already share context, attend the same meetings, have reasons to talk daily. The collaboration that breaks down is between teams. And shared interests are one of the few things that reliably create trust between people who have no professional reason to interact.

We have written about what happens when profiles include interests. People start browsing the org chart to explore. But getting to that point requires more than adding a field.

Why the Company-Wide Email Always Gets Ignored

HR sends a company-wide email: “We’ve added an interests field to your profile! Please fill it in so we can build a more connected workplace!”

That email gets ignored. People aren’t against the idea. It just sounds like homework. It sounds corporate. And it does not answer the question every employee silently asks: “What happens after I fill this in?”

The companies that get participation right do something different. They start with a small group. Five or six people across different departments, including at least one person from leadership, fill in their interests before anyone else is asked. When the announcement goes out, there is already something to look at. New employees can browse profiles and see that someone in engineering makes hot sauce from scratch, the finance lead is into trail running, and a customer support rep has been playing competitive Scrabble since university.

That changes the psychology. People are not filling in a blank form. They are joining a conversation that already exists.

Seeding Groups That Cross Boundaries

One tactical detail we keep seeing make a difference: the first three members of any interest-based group shape its trajectory.

If you start a #running channel and the first three people in it are all from engineering, it will stay an engineering channel. Others will see the member list, decide it is not for them, and move on. But if those first three people come from three different departments, the channel reads as company-wide from day one.

This means you cannot just create channels and hope people show up. You need to personally invite specific people from different teams. You need to know who runs, who bakes, who plays chess. The only way to know that at scale is to have the data somewhere visible and searchable.

When these groups work, the side effects are significant. Someone from Sales needs technical input on a customer problem. Instead of opening a ticket or waiting for a meeting, they message the engineer they ran a half-marathon with last weekend. They send a direct message because they already have a relationship. The difference between a three-day turnaround and a three-minute conversation.

Where It Gets Messy

Some things do not work easily, and pretending otherwise would waste your time.

Some people will not participate. They consider their personal interests private, or they do not want to be “the fun one” at a company where they feel the culture does not support it. That should be fine. Making the field mandatory is a guaranteed way to get sarcastic one-word answers and resentment. Keep it optional. A 60% fill rate is better than a 100% fill rate full of junk data.

Some groups will fizzle. The book club that meets twice and then dies. The photography channel that goes quiet after a month. This is normal. You do not need every group to survive. You need enough of them to create a few real connections. One friendship between a designer and someone in operations, built over a shared love of birdwatching, can change how those two departments work together for years.

Some managers will see this as a distraction. “We don’t need a cooking channel. We need people to hit their deadlines.” This is the hardest objection to address because it is not entirely wrong. Interest groups are not a substitute for clear goals and good management. They are a layer underneath that makes collaboration less painful when it matters. The employees who cannot find each other across departments are the same ones stuck in slow, formal request workflows.

Onboarding Is the Best Moment for This

Buddy programs usually pair new hires with someone from the same team. This makes sense for logistics. But the relationship that helps a new hire feel like they belong is usually not with their team buddy. It is with someone in a completely different part of the company who happens to share an interest.

A new hire who loves photography, matched with someone in a different department who also shoots on weekends. Their first conversation is not about the expense report process. It is about cameras and favorite spots. That conversation makes the new hire feel like a person, not a headcount. Onboarding is about belonging, not information transfer.

Cross-department buddy matching based on interests is the single most underused onboarding tactic. It takes almost no effort if you have interest data visible and searchable.

Two Decisions That Predict Whether It Sticks

After watching this play out at different companies, the pattern is consistent. What predicts whether interest-based connection takes root or dies quietly comes down to a few specific decisions.

Leadership goes first. If the CEO, VP, or department heads fill in their interests, everyone else follows within weeks. If it is positioned as an HR initiative with no executive participation, adoption drops off within a month.

The data is visible, not locked away. Interest surveys that end up in a spreadsheet on someone’s drive are worthless. The information needs to live where people already look, on employee profiles in the tools they use every day. If someone cannot search “who else likes bouldering” across the whole company, the data does not exist as far as they are concerned.

Nobody is forced. The participation rate on an optional field tells you something real about your culture. If people are eager to share, that is a sign of trust. If they are not, mandating it will not fix the underlying problem.

Interest-based connection is a small intervention. It will not fix a broken culture or replace good management. But in a company where remote and hybrid work has eliminated the hallway conversations that used to create cross-department bonds, small interventions are often the only ones that scale.
