Starting a new job

What should I do in my first 90 days?

The first three months set how people talk about you for the next three years. Most of that is decided by listening rather than by output.

The short answer

Three things worth knowing.

  • Spend the first weeks understanding how the work really flows: who decides, what gets rewarded, where things get stuck.

  • Meet people one to one and ask the same three questions each time. The overlaps tell you what the team actually believes.

  • Deliver one small, visible thing early. It buys patience for the bigger work that takes longer.

What to do

A sequence that works.

  1. 01

    Agree what good looks like

    Ask your manager what success at 90 days means, and write the answer down.

  2. 02

    Run listening conversations

    Fifteen people across the teams you depend on, in the first month.

  3. 03

    Ship something small

    A fix, a document, a process nobody owned. Early proof beats a grand plan.

  4. 04

    Check in at week six

    Ask for blunt feedback while it is still cheap to change course.

Common mistakes

What to avoid.

  • Rewriting how the team works before understanding why it works that way

  • Only meeting your own team

  • Waiting for a formal review to ask how you are doing

  • Hiding confusion instead of asking in week one

Questions

The things people ask first.

How long before I stop feeling new?

Usually one full cycle of the work, which is three to six months in most jobs.

Should I mention things that seem broken?

Yes, as questions rather than verdicts, and after you understand the history.

What if the job is not what was described?

Raise it early and specifically with your manager. Six months of silence makes it harder, not easier.
