The first 90 days: making a new job stick

Probation is not a skills exam: your skills already convinced, or you would not be there. What is decided in the first weeks is trust, and it is built on precise signals that most newcomers neglect because they want to prove too much, too fast.

The first month: understand before changing

The most expensive reflex of month one is proposing changes before understanding why things are the way they are. Every strange procedure has a history, often a good reason buried underneath. Month one's job is an inventory: who decides what, who knows what, where the real circuits run. Asking questions does not dent credibility, quite the opposite: a precise question is the first proof of seriousness. Keeping a notebook of surprising things pays off later: after three months, you no longer see them.

Deliver small and early

The first delivery counts double, whatever its size. A clean document, a fix, a short analysis: the object matters less than having finished something end to end within the first three weeks. The symmetrical trap is the big project started early that only lands in month four: all that time, nobody saw anything.

Make work visible without selling

Between invisibility and self-promotion sits a simple gesture: the short written status update, regular, addressed to the person who needs to know. What I finished, what is in progress, what is blocked. Three lines a week are enough. This is not communication, it is work: a manager who knows where you stand does not need to come and check.

The fresh-eyes report: the tool nobody uses

Around week six, a view still fresh but already informed is worth gold. Two pages: what works remarkably well, what surprises, three concrete leads. Handed over unprompted, this document does two things: it shows observation skills, and it turns corridor remarks into a contribution. The condition: as many things that work as leads for improvement, otherwise it reads as a list of complaints.

If the job is not the one promised

A gap between the ad and reality is handled early and factually: “the ad described this, I spend my time on that, how do you see it”. Raised in month two, that conversation corrects course or clarifies what comes next. Postponed past probation, it becomes a grievance. Probation works both ways: you are also deciding whether this employer deserves your years.

Allies are chosen early

In every team, two or three people hold the memory of the place: why a choice was made, who to consult before touching what. Identifying them in the first two weeks and asking for an hour changes the speed of everything else. Lunch with a colleague from another department is worth its hour too: organisations are understood from their edges, not their centre. And the person who hired you deserves a mid-probation check-in, requested by you: reaching the deadline with no interim feedback means discovering the verdict once it is already given.
