Your colleagues form opinions of you before you've finished your second week — fair or not. The first 90 days are when those opinions calcify. Here's what we coach our placed candidates to focus on.
Listen before you talk
The biggest mistake new hires make is arriving with answers. Use weeks one to three to ask, observe and take notes — not to redesign the team's workflow. The people who built the existing system aren't stupid; if something looks wrong, you're likely missing context you'll have by week six.
Deliver one visible win early
Find one thing — a small fix, a clean piece of analysis, a process tightened — and ship it inside thirty days. It does not need to be heroic. It needs to be done. That first delivered piece of work anchors how people remember you for the rest of the year.
Be honest about what you don't know
Faking competence to look strong now creates a much bigger debt three months from now. People respect "I don't know yet, I'll find out by Thursday" far more than a confident wrong answer. The senior people in the room are doing exactly this — they're just better at it.
Have the right early conversations
Schedule one-to-ones with your peers and key stakeholders in your first three weeks. Not to pitch yourself — to ask what they're dealing with, what they expect from your role, and what good looks like to them. The conversation itself signals you take the work seriously.
Set expectations with your manager — in writing
Agree on what success looks like at 30, 60 and 90 days. Get it in an email or document. It removes an entire category of performance anxiety, and gives you something honest to review against — instead of guessing whether you're meeting an invisible bar.
What this builds
Trust compounds. The candidate who listens, ships one clean thing, asks good questions and reviews against agreed milestones is the candidate who gets handed the bigger problem in month four. That's where the real career growth lives — and it almost always traces back to the first 90 days.
