About to start a new job? Your first 90 days can make or break you

I couldn’t be happier.
Over the last few weeks, several clients have landed jobs!

You might think coaching ends there: “ job done!”.
Not at all!
In fact, that’s where the real work starts.

You’ve found the job, you’ve closed a long chapter of searching…
But your onboarding can make or break what comes next, for you AND for your company.

Today, I an breaking it down and share the foundations of a successful onboarding.

But first, here’s the biggest mistake almost everyone makes, even senior professionals:

They wait.
They wait to get things very clear, for the “full picture,” to understand the culture, the product, the business…
They wait before speaking up or sharing ideas.

That’s wrong. And not only this is wrong, it can be used against you at the end of your probation period.

Sharing a quick story from one of my clients

Ella had just landed a global role after months of searching.
She wanted to make a strong impression.

Week 1: Her calendar was packed. She logged in early, read everything she could, and jumped from meeting to meeting during the day
Week 2: Still overwhelmed with meetings, she wasn’t driving her agenda. She tried catching up late at night and early morning.
Week 3: She felt she’d already lost control. Everyone assumed she was ok because she looked “independent,”
but inside she felt unsure and ended up questioning her own abilities. (I met her weeks later, she was, in fact, an exceptional leader)

If you want to own your success, start here:

1. Get clear on expectations, and fast

Ask your manager early:
• What does success look like in 30/60/90 days?
• What would be a quick win this month?
• How will we measure progress?

Don’t be shy about asking these questions! It can be the turning point of your first month.

2. Build relationships intentionally

Don’t wait to be introduced. I am always encouraging my clients to reach out, book short catch-ups, and start conversations.
Visibility is built one person at a time.

3. Create your own structure

Onboarding often fades after week 2.
So build your own plan:
• What you need to learn
• Who you need to meet
• What outcomes matter most

All these strategies, I’m sharing them week after week with the leaders I work with. I keep them accountable for their actions, and I help them stay focused on their North Star. A successful onboarding where they don’t miss any opportunity to thrive.

⭐ Next week…
I’ll go one level deeper and talk about something just as essential:
setting boundaries from day 1 — without looking difficult.

Clarity is one thing.
Protecting your energy is another.

🎯 I’m onboarding only 5 new leaders to start in January 2026 (4 spots left). If you are curious to know how Career Coaching can help in your situation, reserve your free confidential conversation here
