I still remember the anxiety I felt before my first day at my first real job. Would I know where to go? What to bring? Who to talk to?

Fast forward to when I was running Simpo, and I was on the other side. A new hire showed up for their first day, and I realized I had no plan. No checklist. No onboarding materials. Just me scrambling to figure out where they should sit and what computer to give them.

It was a disaster.

I’m Yuval, founder and CEO of Glitter AI. After running two startups and hiring dozens of people, I’ve learned that great employee onboarding isn’t about making a good first impression. It’s about setting people up to actually succeed in their role.

Here’s the thing: a proper onboarding checklist isn’t just an HR nicety. It’s the difference between someone who’s productive in a month versus someone who’s still confused six months in.

Let me share the complete employee onboarding checklist I wish I’d had from day one.

Before Day 1: Pre-Onboarding Checklist

The onboarding process actually starts before your new hire walks through the door. This is where you set the tone and prevent that first-day scramble.

Immediately After Offer Acceptance

Send a welcome email with:

Complete administrative setup:

Prepare onboarding documentation:

One Week Before Start Date

Confirm logistics:

Prepare the team:

Create the first week schedule:

Here’s a template for the first week I use:

Day 1: Orientation, IT setup, team introductions Day 2: Role-specific training begins, shadow team members Day 3: Continue training, first small task or project Day 4: Meet with manager for role expectations discussion Day 5: Wrap up first week, check-in meeting

First Day Checklist

The first day sets the tone for everything that follows. Make it count.

Morning (First 2-3 Hours)

Welcome and orientation:

IT and administrative setup:

Provide essential resources:

Afternoon

Role overview meeting with manager:

Initial training begins:

End of day check-in:

The biggest mistake I made early on? Overwhelming new hires with information. Now I pace things and check in frequently to make sure they’re not drowning.

First Week Checklist

The first week is about building foundation and context.

Daily Check-Ins

Meet with the new hire every single day:

Key First Week Activities

Complete essential training:

Shadow team members:

Assign first small tasks:

End of Week Review

Friday check-in should cover:

I like to do this as a casual conversation, maybe over coffee. It creates psychological safety for them to be honest.

30-60-90 Day Onboarding Checklist

The first three months are where new hires either gain confidence or start looking for other jobs.

30-Day Checklist

By the end of month one, new hires should:

Understand the company:

Understand the bigger picture:

Be engaged and committed:

90-day formal review:

Documentation Needed for Effective Onboarding

Here’s what drove me nuts at Simpo: we’d explain the same things over and over to each new hire. Same questions, same answers, repeated endlessly.

Create these core onboarding documents:

Company overview:

Administrative guides:

Role-specific documentation:

Cultural and practical info:

Creating Self-Service Onboarding Materials

Here’s what changed everything for me: making onboarding materials self-service.

Instead of having managers repeat the same training over and over, create resources new hires can consume at their own pace.

Types of Self-Service Materials

Video training:

Written guides:

Interactive learning:

Just-in-time resources:

The beauty of self-service materials? They scale. Whether you’re onboarding one person or ten, the effort is the same.

Role-Specific Onboarding Variations

Not every role needs the same onboarding process. Here’s how I think about customizing.

Technical Roles (Engineers, Developers)

Additional focus areas:

Unique first tasks:

Sales and Customer-Facing Roles

Additional focus areas:

Unique first tasks:

Operations and Administrative Roles

Additional focus areas:

Unique first tasks:

Management and Leadership Roles

Additional focus areas:

Unique first tasks:

The key is identifying what’s universal for all new hires versus what’s specific to the role.

Measuring Onboarding Success

How do you know if your onboarding is actually working? Here are the metrics I track.

Quantitative Metrics

Time to productivity:

Retention rates:

Training completion:

Manager time investment:

Qualitative Feedback

New hire surveys:

Manager feedback:

30-60-90 day check-ins:

I send an anonymous survey at the 30-day mark and again at 90 days. The feedback has been invaluable for refining our process.

Red flags:

Common Onboarding Mistakes (And How to Avoid Them)

Mistake 1: Information Overload

What it looks like: Dumping everything on new hires in the first week. Eight hours of presentations on day one. Hundreds of documents to read.

The problem: Humans can’t absorb that much information at once. Most of it goes in one ear and out the other.

The fix: Pace information delivery. Introduce concepts when they’re relevant. Create just-in-time resources instead of front-loading everything.

Mistake 2: No Clear Structure

What it looks like: “Just shadow people for a few weeks and figure it out.” No schedule, no clear milestones, no expectations.

The problem: New hires feel lost and anxious. They don’t know what they should be learning or if they’re on track.

The fix: Create a detailed onboarding schedule with clear learning objectives for each week. Set explicit 30-60-90 day goals.

Mistake 3: Outdated or Missing Documentation

What it looks like: Handing new hires materials that reference old systems, processes that have changed, or tools you no longer use.

The problem: Erodes trust. If the official documentation is wrong, new hires learn to ignore documentation and just ask people instead.

The fix: Assign ownership for keeping onboarding materials current. Review and update at least quarterly. Get feedback from recent hires on what was outdated.

Mistake 4: One-Size-Fits-All Approach

What it looks like: Every new hire gets exactly the same onboarding, regardless of role, experience level, or background.

The problem: Wastes time on irrelevant content. Doesn’t address role-specific needs. Experienced hires feel patronized.

The fix: Create modular onboarding with core universal content plus role-specific tracks. Adjust based on experience level.

Mistake 5: Focusing Only on Tasks, Not Culture

What it looks like: All training is about what to do and how to use systems. Nothing about team dynamics, company values, or how to be successful here.

The problem: New hires might learn the mechanics but miss the unwritten rules about how things really work.

The fix: Explicitly teach culture. Explain how decisions get made, what behaviors are valued, what success looks like beyond metrics.

Mistake 6: Set It and Forget It

What it looks like: Creating onboarding materials once and never updating them. Not gathering feedback or measuring effectiveness.

The problem: The business changes but onboarding stays static. Missed opportunities to improve.

The fix: Treat onboarding as a living process. Collect feedback from every new hire. Review metrics quarterly. Continuously refine.

Building Your Onboarding Checklist: Where to Start

Feeling overwhelmed? Here’s how to build an effective onboarding process from scratch.

Step 1: Document Your Current State

Map out what happens now:

Just write it all down. Even a messy starting point is better than nothing.

Step 2: Define Success Criteria

What should new hires be able to do:

Be specific. “Understand the product” is vague. “Complete product certification quiz with 90% accuracy” is measurable.

Step 3: Create the Core Checklist

Start with the universal stuff:

Use the checklists in this guide as a starting point and customize for your company.

Step 4: Build Essential Documentation

Prioritize these materials:

  1. First day orientation guide
  2. How to access key systems and tools
  3. Who to ask for what (contact guide)
  4. Training manuals for core processes
  5. Company overview and culture guide

Step 5: Assign Ownership

Clarify who owns what:

Step 6: Test and Refine

Run your new process with the next hire:

Final Thoughts

Here’s what I wish I’d understood earlier: great onboarding isn’t about impressing new hires. It’s about setting them up to succeed.

The companies with the best retention, the highest performance, and the strongest cultures? They nail onboarding.

They make new hires feel welcomed. They provide clear expectations. They give people the resources and support they need to learn. They measure what’s working and continuously improve.

Most importantly, they don’t treat onboarding as a one-week event. It’s a 90-day journey that starts before day one and continues well into month three.

Your onboarding checklist doesn’t need to be perfect. It needs to be clear, comprehensive, and actually used.

Start with the basics in this guide. Customize for your company and roles. Gather feedback and improve it over time.

And remember: every hour you invest in great onboarding saves you dozens of hours down the road in confusion, re-training, and preventable turnover.

Your future self (and your new hires) will thank you.

Frequently Asked Questions

What should be included in an employee onboarding checklist?

An effective employee onboarding checklist should include pre-boarding tasks (IT setup, workspace preparation), first day activities (orientation, introductions, admin paperwork), first week training (company overview, tools training, initial tasks), and 30-60-90 day milestones. Include both administrative items and role-specific training, and assign clear ownership for each task.

How long should the employee onboarding process take?

Most companies use a 90-day onboarding period, though new hires should be functional in their core role within 30 days. The first day covers basics and orientation, the first week includes essential training, and months 2-3 focus on increasing independence and expertise. Technical or senior roles may need longer onboarding periods.

What's the difference between orientation and onboarding?

Orientation is typically a one-time event covering company basics, paperwork, and administrative setup. Onboarding is the comprehensive 90-day process of integrating new hires into the company culture, training them on their role, and helping them become productive team members. Orientation is a small part of the larger onboarding journey.

Who should be responsible for employee onboarding?

Onboarding is a shared responsibility. HR typically coordinates logistics and administrative tasks. The direct manager owns role-specific training and performance expectations. An onboarding buddy helps with day-to-day questions and cultural integration. IT handles system access and equipment. The key is clearly defining who owns each piece.

How can I measure if my onboarding process is effective?

Track time to productivity (how quickly new hires can work independently), retention rates at 90 days and beyond, training completion rates, and new hire satisfaction scores. Gather feedback through surveys at 30, 60, and 90 days. Strong onboarding shows up in faster productivity, higher engagement, and better retention compared to industry benchmarks.

Should remote employees have a different onboarding checklist?

Remote onboarding requires the same core elements but with additional focus on virtual connection, technology setup, and communication norms. Include extra check-ins to prevent isolation, virtual team introductions, clear remote work policies, and over-communicate expectations since casual in-person questions aren't possible. The 30-60-90 day framework still applies.

What are the most common onboarding mistakes to avoid?

The biggest mistakes are information overload on day one, lack of clear structure or expectations, outdated documentation, one-size-fits-all approaches that ignore role differences, focusing only on tasks without teaching culture, and treating onboarding as a one-week event instead of a 90-day process. Also avoid 'set it and forget it' - successful onboarding requires continuous improvement.

How do I create self-service onboarding materials efficiently?

Start by recording yourself or experienced employees performing common tasks while explaining the process. Turn these recordings into step-by-step guides with screenshots using tools like Glitter AI. Create searchable documentation that new hires can access when needed, rather than scheduling live training for everything. Build a core library of FAQs, process guides, and video tutorials that scale as you grow.
