Every time I changed companies, someone told me the same thing: “you’re starting from zero again”. Six companies later, I can say with some confidence that this is false.
What you carry with you
What doesn’t transfer is context: who decides what, where the wires run, why that one service has a weird name. You relearn that — and it takes three to six months no matter how senior you are.
What does transfer is repertoire. You’ve seen a deploy go wrong at 11pm. You’ve seen a project die for lack of an owner. You’ve seen a team recover from a bad decision. None of that resets.
The first thirty days
In the first few weeks I always do three things:
- Listen more than I talk. The urge to prove value fast is the biggest trap of changing jobs.
- Map who knows what. The org chart is fiction; the real network of people who get things done is another thing entirely.
- Ship something small and visible. Not to impress — to understand the full path of a change, from commit to production.
What I’d do differently
I’d have asked more about the problem and less about the stack. The technology in a job ad changes in two years. The kind of problem a company solves doesn’t.
If you’re thinking about moving: you’re not starting from zero. You’re starting with a repertoire nobody in that room has.
