Onboarding Is Not a Honeymoon. It's a Marathon That's Already Started.
When I was a teacher, I loved the start of a new school year.
Every student at the same starting line. Same classroom, same content, same teacher. And within weeks — sometimes days — the marathon would reveal itself. Leaders emerging. Students falling behind. The quiet ones who’d surprise you three months in because they just kept going. The technically brilliant ones who couldn’t translate it under pressure.
The thing I noticed most: almost every outcome traced back to what happened in those first few weeks. What the student believed about themselves. Whether someone stayed with them when things got hard. Whether the environment gave them room to struggle without quitting.
I’ve been in enough technical onboarding programs now — as a new hire, as a mentor, as someone building them — to know the same marathon plays out in every org. Same starting line. Same sprint of excitement in week one. Same divergence by month two.
And I’ve been every position in that marathon, depending on where I landed.
The honeymoon phase is real. New hires are expected to absorb, not perform. Watch the videos. Shadow the calls. No quota pressure, no customer expectations. It feels safe. And then it ends.
Trial by fire begins the day official onboarding closes. Most new SEs can’t handle the jump — not because they didn’t try hard enough, but because nothing in the onboarding simulated what they were about to face. The content was accurate. The scenarios were clean. The real world is neither.
When a new hire is still looking green on calls six weeks after onboarding ends, the instinct is to question the hire. The harder question is: what were we actually preparing them for?
Here’s what I’ve come to believe: content is the map. But you don’t get good at the terrain by studying the map.
The recordings, the playbooks, the certification paths — all of it is necessary. None of it is sufficient. What closes the gap is the live customer call you debrief afterward. The moment a senior SE watches you work and tells you specifically what they saw. The scenario that breaks your standard approach and forces you to figure something out on the spot.
The map gets you oriented. The terrain is where you actually learn to navigate.
What activates the learning is real friction from the real world. A manager who protects time for this before the pressure arrives. A mentor who stays in the marathon with you past the honeymoon phase. And the individual who keeps going even when the gap feels impossible to close.
That last part isn’t something you can design. But the first two are. And most orgs leave all three to chance.
No magic. Just the work — and someone in your corner while you do it.
What’s the moment from your own onboarding that actually made you ready? Not the content — the moment.
