Your first 4 weeks should get new hires up to speed, help you understand their strengths, identify where they need support, and ensure they’re ready and confident for client work.
Before someone goes onto client work, they need to understand how your agency operates. The best way to learn is by doing.
So have them do an assignment as soon as they start.
As a byproduct, if there are any serious red flags, you’ll spot them early. But that’s not the goal. The goal is setting people up for success.
Step 1: design the assignment
Before they start
Identify the skills and behaviours someone needs to serve your clients and be valuable. Design a two-week assignment that gives them opportunities to demonstrate these skills in the context of how your agency actually works.
The assignment should:
- Mimic real client work
- Include a brief, research, milestones, and team interactions
- Allow them to present, explain work, collaborate, take feedback, and iterate
- Test the behaviours of a good team member
What it should test
Your assignment should put your new hire into situations where they can demonstrate the necessary skills and your good behaviours. It won’t always be possible, so prioritise.
Take your behaviours and identify which are riskiest to long-term success. Make sure the assignment tests these.
For example:
- If you need someone to be credible in front of clients → get them into a client meeting
- If you value being prepared → observe the questions they ask beforehand about the client
- If you value collaboration → make part of the assignment collaborative
The three-level brief
Your assignment brief should have parts that are detailed but also leave areas open-ended.
Level 1: detailed brief
Be explicit about a deliverable and the format required. Use a format you use often.
This shows you: Can they follow detailed instruction?
Level 2: loose prompt
Prompt them for a deliverable you don’t have the format for yet.
This shows you: How do they create something new? Do they get sign-off? Just do it? Get stuck?
Level 3: open request
Ask if there’s anything else that would make this work better. An extra piece of research or asset.
This shows you: Do they show initiative? Do they think beyond the brief?
Step 2: week 1 — welcome them and brief them
Their first week
Get them set up with standard onboarding (meet people, learn software, read the handbook, health and safety).
Then brief them on the assignment.
Step 3: weeks 2–3 — the assignment itself
Two weeks of doing
They complete the assignment. You’re available and checking in. They work with the team. You observe how they work and where they shine.
Your role:
- Be available for questions and collaboration
- Schedule a formal check-in at end of week 2
- Check in informally throughout
- Make it clear that asking for help is expected and valued
What you’re observing:
- Their strengths and where they shine
- Where they might need support
- How they work with the team
- How they handle feedback
Step 4: week 4 — feedback and next steps
The decision point
A formal but friendly review. Get feedback from everyone who has worked with them and — importantly — ask them to run through how they are settling in, what they are finding easy and what they are finding hard.
Point out what they did really well. Identify areas where they might need support. Decide on next steps.
Most of the time: they’re ready for client work.
Sometimes: they need more support in specific areas first.
Rarely: they’re not the right fit (but you know in week 4, not week 12).
Important notes
On psychological safety
Starting a new job is stressful. You don’t know what’s going on in someone’s life. They might be having difficulties behind the scenes that affect their performance on this assignment.
This only works if there’s psychological safety. They need to feel safe asking questions, making mistakes, and being honest about what they’re struggling with.
This is really good onboarding — it’s not about catching people out. Make sure they know that.
On getting team feedback
This feeds into your wider culture of feedback. You’ll know from how keen team members are to collaborate with this new person and whether they want them on their projects.
Ask:
- What are this person’s strengths? Where did they shine?
- What might they need support with as they settle in?
- What should I know to help set them up for success on client work?
- Would they be a good fit for your next project?
On timing
If they finish early:
This might mean they’re efficient, or it might mean they didn’t go deep enough. Look for self-awareness: “I finished early, I could have explored X more.”
If they run out of time:
This might mean they’re thorough, or it might mean they struggled with prioritisation. Again, get their opinion: “I ran out of time, I should have focused on X first.”
Both tell you something useful about how they work and what support they might need.
Outcome
Most of the time, people are ready for client work and you’ve identified how to support them. Sometimes they need more focused support first. Rarely, they’re not the right fit — but you know by week 4, not week 12 when they’re embedded in projects.
