Practical advice for candidates - whether you're starting out or stepping into a senior role.
Starting a new job always brings a mix of emotions. Whether it’s your first step into work or the first time you’ve changed roles in years, there’s often a quiet question running in the background:
“How do I show I’m the right person for this job - without trying too hard or getting it wrong?”

At MDR Consultancy, we’ve supported people at every stage of their career, and we know that those first few months matter more than most people realise. Not because you need to be perfect, but because it's when you build your reputation, establish trust, and start shaping how others see you.
This isn’t about proving yourself by day three. It’s about being intentional, understanding the culture, learning where you can add value, and presenting in a way that is authentic and feels like you.
Whether you’re managing a team or joining one, here’s our grounded approach to making an impact in your first 90 days.
The Role of the First 90 Days
Most employers won’t expect you to hit full stride right away, but they will be forming impressions. The first few months are often a time of informal assessment: how do you work? What’s your attitude? Do you listen? Take initiative? Fit into the pace and values of the business?
This phase isn’t about being perfect or flashy it’s about being present.
You’re not just learning the job. You’re learning how that job fits into the team, the culture, and the bigger picture.
A Practical Way to Think About It: 30 / 60 / 90
Days 1–30: Observe, Ask, Absorb
Learn the landscape. Who does what? How do things get decided? What are the unspoken norms?
Ask good questions. It’s a strength not a weakness to be curious. Don’t wait for formal training to understand what matters.
Take notes. Not just on tasks, but on tone: how do people work here? Where could things be clearer or smoother?
Introduce yourself with intention. Speak to people outside your team, when possible, you’re not just a new name, you’re part of the business now.
Tip: Not wanting to teach you to suck eggs but, if you're stepping into a management role, resist the urge to make big changes straight away. Use this time to understand how things work and why.
Days 31–60: Start Contributing, Stay Curious
Look for ways to add value. Whether it’s picking up a process, improving a task, or helping someone out contribution builds credibility.
Connect the dots. Start joining what you’ve observed with what you’re doing. Spot patterns, issues, or opportunities.
Give and seek feedback. This isn’t about formality just check in. “Am I on the right track?” goes a long way.
Share your progress. It’s not about self-promotion it’s about communication. People like to know you’re settling in and contributing.
Manager or not, this is the phase where people want to see your confidence grow. Let it show in how you carry yourself and how you connect with others.
Days 61–90: Show Direction and Momentum
Start leading your role. By now, you should have a sense of where you’re heading and the confidence to shape your own contribution.
Bring ideas — carefully. If something doesn’t quite work, raise it constructively. Thoughtful insight shows you’re not just ‘new’, you’re engaged.
Review and reflect. Look back at what you’ve learned, done, and still want to improve. Ask yourself: “Where do I want to be by month six?”
Continue connecting. Don’t stop building relationships. This is how collaboration and trust develop over time.
If you're feeling like you're only just finding your feet at day 90 that's okay. Every role and every culture is different. The point isn’t to ‘finish’ onboarding. It’s to begin with purpose.
Common Pitfalls to Avoid (And What to Do Instead)
Pitfall | Do this instead |
Trying to prove yourself too quickly | Focus on building trust through listening and small, useful contributions |
Saying yes to everything | Be thoughtful offer help where it matters, not everywhere at once |
Staying too quiet for too long | It’s normal to be cautious, but you’re part of the team now don’t wait too long to speak up |
Expecting it to feel right straight away | Give yourself space to adjust. Settling in takes time |
What Success Really Looks Like by Day 90
Forget trying to tick every box. What really matters is that you’ve:
-Built a foundation of trust
-Contributed something meaningful
-Asked smart questions
-Started building strong relationships
-Felt your own confidence begin to grow
If you’ve done those things you’re exactly where you need to be.
Final Thought
You don’t need to reinvent the wheel in your first 90 days. You don’t need to be the loudest, fastest, or most impressive. You just need to be present, intentional, and open to learning.
Whether you're navigating a first job or a step into something more senior, it’s okay not to know it all. What matters is how you show up.
And if you’d like a sounding board along the way whether it’s career advice, interview prep or helping you shape what’s next the team at MDR is always here.
