Getting the offer is the end of everything this course has covered so far, and the start of an entirely different set of adjustments. The first ninety days set the tone for how a new team sees you, and a few honest expectation resets make that period considerably less disorienting.
The first weeks are mostly about the codebase, the tools, and the team being unfamiliar all at once — this is normal, expected, and not a sign of falling behind. Most teams budget real ramp-up time for a new junior precisely because they know this. Panicking about not yet being fully productive in week two is a much bigger problem than actually not being fully productive in week two.
| What to prioritise | Why |
|---|---|
| Asking good questions | Far better than silently guessing and shipping something wrong |
| Understanding before changing | Read and genuinely understand existing code before modifying it confidently |
| Following existing conventions | Even ones you'd personally do differently — consistency matters more than personal preference early on |
| Being reliable on small things | Small, correctly finished tasks build trust faster than one ambitious, unfinished one |
| Taking notes | You will be told the same thing only once in most teams — write it down |
Nobody expects a new junior to know everything, but there is a real difference between a well-formed question and a vague one. "I looked at X and Y, I think it might be Z, but I'm not sure — could you confirm?" respects the other person's time and shows real effort. "How does this work?" with zero attempt made first does not, and wears thin quickly on a busy team.
Keep a running list of questions and batch them where reasonable, rather than interrupting a colleague every few minutes. This is a genuine courtesy on a busy team, and it is also just a more efficient way to actually get unstuck.
Not to become an expert. To become someone the team trusts with small, well-defined tasks, who asks reasonable questions, and who is clearly still learning but visibly improving. That is a genuinely realistic bar for ninety days, and hitting it sets up everything that comes after.
