Your First Day Checklist: For Apprentices, Trainees, and Anyone Just Starting Out in the World of Work
Call 0116 303 3560
If you’re between 18 and 22 and stepping into your first proper job – whether it’s in an office, a finance team, or as an apprentice – this first day guide is for you.
You’ve hopefully smashed your interview after reading our Interview Confidence Booster, and now you’re about to start the job!
But let’s be honest: your first day can feel a bit scary. You want to make a good impression, but you’re not quite sure what to expect. That’s completely normal. Everyone has a first day – and we’re here to help you make yours a success.
At Optima UK, we support young people starting their careers every day. So here’s your First Day Checklist to help you walk in feeling prepared, confident, and ready to smash it.
First impressions start before you even step through the door. Turning up well-prepared shows your new employer you’re reliable and switched-on.
✔ Know What Time You Need to Be There
Double-check your start time and how long it’ll take to get there. Aim to arrive 10–15 minutes early – it gives you time to find the building, breathe, and avoid any last-minute stress.
✔ Check What to Wear
Not sure about dress code? Smart casual is usually safe. Think clean, tidy, and put-together – avoid joggers, hoodies, or anything too scruffy.
✔ Bring the Right Stuff
You might need to bring ID, bank details, or proof of your right to work. Ask your recruiter or check your welcome email so you don’t turn up empty-handed.
✔ Pack a Notebook & Pen
You’ll be given loads of information – from passwords to names and systems. Having something to jot it all down shows you’re organised and ready to learn.
✔ Think of One or Two Questions
You don’t need to grill anyone, but having a couple of questions in mind (e.g. “What’s the usual lunch routine?” or “What does a typical day look like?”) shows interest.
Your attitude on day one matters – a lot. Even if you’re nervous (and you probably will be), how you act will stick in people’s minds.
✔ Smile and Say Hello
Even if you’re shy, a smile and a simple “Hi, I’m [Your Name] – nice to meet you!” goes a long way. You’ll likely forget names, but don’t worry – everyone does.
✔ Be Keen (Not Over-the-Top)
You don’t need to pretend to know everything – in fact, don’t. Just show that you want to learn. Say yes to small tasks, listen carefully, and ask if you’re not sure.
✔ Pay Attention to Body Language
Sit up straight, keep your phone away, and make eye contact. These small things help people see you as focused and approachable – even if you’re a bag of nerves inside.
✔ Watch the Vibe
Is the office chatty or quiet? Do people take lunch at their desks or together? Are emails super formal or more relaxed? Picking up on this early will help you fit in faster.
You’re not expected to become best mates on day one – but showing you’re friendly and polite will help build strong working relationships.
✔ Try to Remember Names
Repeating someone’s name can help it stick. “Nice to meet you, Sarah!” If you forget later, just be honest and ask again – people understand.
✔ Learn Who’s Who
It’s helpful to know who your line manager is, who handles IT, and who’s on your team. You’ll feel more settled once you understand how things are structured.
✔ Be Open to Small Talk
Even a quick chat about the weather or weekend plans can break the ice. If someone invites you to lunch or a tea break – go! It’s a great chance to settle in socially.
The first few days are all about soaking up knowledge. You’re not expected to know everything – but it helps if you show you want to.
✔ Take Notes (Seriously, Do It)
Write down system logins, processes, names of key people – anything you think might be useful. It’ll save you from asking the same thing five times.
✔ Notice How the Team Works
Do they use Teams? Slack? WhatsApp? Do people call or email more? Learning the tools and communication style will make your life easier.
✔ Ask Questions Early
If you’re unsure, speak up. It’s better to ask now than get something wrong later. You’ll actually come across as more capable, not less.
✔ Know What’s Expected of You
By the end of the day, try to get a sense of:
– What your main responsibilities are
– Who you report to
– What a “good job” looks like in this role
✔ Thank Your Manager
Before you leave, say a quick thanks. “Thanks for today – I’ve learnt loads and I’m really looking forward to the rest of the week” is more than enough.
✔ Optional: Send a Follow-Up Email
If you want to stand out, you could send a short email the next morning.
Subject: Thank You – First Day
Hi [Manager’s Name],
Thanks again for such a warm welcome yesterday. I really enjoyed meeting the team and learning about the role. I’m excited to get stuck in and appreciate any feedback as I settle in.
Best regards,
[Your Name]
✔ Reflect When You Get Home
What went well? What felt awkward? What do you want to do differently tomorrow? A quick mental recap will help you grow quickly in your new role.
You don’t have to be perfect on your first day. You just need to show that you’re ready to learn, willing to work, and keen to be part of the team.
At Optima UK, we know how nerve-wracking those early days can feel – but we also know how capable you are. By following this checklist, you’ll make a great impression and give yourself the best start to your working life.
