According to Jorgen Sundberg, CEO and Founder of Link Humans, poor onboarding can cost companies up to $240,000 per bad hire. Yet, a Gallup study on onboarding has found that 88% of organizations admit their onboarding process needs improvement. Employee onboarding is a nuanced process that is quite open to common and costly mistakes. In this article we will be going over just what those mistakes are and how you can avoid them. These common onboarding mistakes destroy new hire confidence and drive talented employees away before they even start contributing.
4 Proactive Steps to Audit Your Onboarding Mistakes
Identifying onboarding mistakes before they impact your retention rates requires a proactive, data-driven approach. According to SHRM’s 2026 State of the Workplacereport, 51% of workers who view their organization’s initial support as ineffective are likely to leave within the year. In a cooling labor market, you cannot afford to wait for exit interviews to find out why a new hire didn't "stick."
To ensure you aren't falling into common traps, follow these steps:
Shadow the Candidate Journey: Walk through your own process as if you were a new hire. Are the instructions clear, or is the "paperwork" burden creating immediate friction?
Leverage Predictive Feedback: Don't wait 90 days. Send a "Day 3" pulse survey to catch early onboarding mistakes like lack of equipment or vague manager introductions.
Analyze Early Turnover Data: If employees are leaving within 45 days, your preboarding or role clarity is likely the culprit.
Consult Your "Buddies": Ask your current onboarding buddies what questions they get asked most frequently. This is the fastest way to identify gaps in your formal training materials.
TL;DR — Quick Summary
Costly Impact: Poor onboarding costs up to $240,000 per bad hire, with 20% of new hires quitting within 45 days without proper preboarding.
Mistake #1 - No Preboarding: Send welcome packages 3 weeks before start date, technology setup 2 weeks prior, and confirmation calls the day before.
Mistake #2 - Information Overload: Use micro-learning modules (10-15 min max) and progressive disclosure—people forget 90% of information within a week.
Mistake #3 - Vague Expectations: Provide specific 30-60-90 day goals, clear success metrics, and structured first-week activities with daily check-ins.
Mistake #4 - No Social Connection: Implement buddy systems with daily check-ins week 1, 3x weekly conversations weeks 2-4, and ongoing support.
Mistake #5 - No Follow-Up: Extend onboarding 90+ days with weekly 1-on-1s, pulse surveys at 30/60/90 days, and continuous feedback loops.
Employees with strong workplace friendships are 7x more engaged and show 50% higher retention—social onboarding drives performance.
Extended onboarding programs (90+ days) result in 50% higher retention and 62% higher productivity compared to short-term programs.

7 Reasons to Prioritize Fixing Your Onboarding Mistakes
In 2026, the cost of losing a new hire isn't just financial—it's a blow to your team’s momentum and your employer brand. According to Gartner, poor onboarding processes can increase manager fatigue by as much as 42%, as leaders struggle to bridge the gaps left by a disjointed start.
Addressing onboarding mistakes early ensures that your investment in recruitment doesn't go to waste. When you refine your process, you achieve more than just "paperwork completion":
Higher Retention: Companies that fix common onboarding mistakes see significantly higher long-term loyalty.
Faster Time-to-Productivity: Clear processes help new hires contribute to the bottom line weeks sooner.
Stronger Culture: A smooth start signals a healthy, organized workplace.
Reduced Stress: Eliminating ambiguity lowers anxiety for both the new hire and the manager.
Better Data: Structured onboarding allows you to track what’s working and what isn't.
Employee Advocacy: Happy new hires become your best recruiters through word-of-mouth.
Resource Efficiency: Automation prevents HR teams from burning out on repetitive manual tasks.
Mistake #1 – No Structured Preboarding Process
The biggest onboarding mistake happens before your new hire even walks through the door. Without a structured preboarding process, new employees feel forgotten, anxious, and disconnected from your organization during the critical period between accepting the offer and starting work.
Why Preboarding Matters More Than Ever
The research we referred to above also shows that 69% of employees are more likely to stay with a company for three years if they experienced great onboarding. Preboarding sets the tone for this entire employee experience and addresses the natural anxiety that comes with starting a new job.
Modern employees expect seamless digital experiences in their personal lives, and they bring these same expectations to work. A disorganized preboarding process signals that your company lacks attention to detail and doesn't prioritize employee experience.
Impact of Poor Preboarding:

Increased first-day stress and overwhelm
Delayed productivity and time-to-value
Negative first impressions that persist
What to Send Before New Hire's First Day?
Effective preboarding creates excitement and reduces first-day anxiety. Your preboarding communication should provide essential information while building anticipation for the new role.
Mistake #2 – Overloading New Hires With Information
Information overload is one of the most common onboarding problems that derails new employee success. When you dump everything on new hires at once, they retain almost nothing and feel overwhelmed instead of empowered.
The Psychology of Information Fatigue
The human brain can only process a limited amount of new information at once. When you exceed this capacity, new employees experience cognitive overload, leading to poor retention and increased stress levels.
Studies show that people forget 50% of new information within an hour and 90% within a week without proper reinforcement. This is why the traditional "drinking from a fire hose" approach to onboarding fails so consistently.
Signs of Information Overload:
Glazed looks during training sessions
Repeated questions about basic information
Inability to complete simple tasks
Visible stress and frustration
Decreased engagement in meetings
How to Onboard New Hires without Overwhelming Them?
Smart onboarding spreads information across time using spaced repetition and progressive disclosure. This approach improves retention while reducing overwhelm.
Mistake #3 – Vague Role Expectations and Poor First-Day Planning
Nothing kills new hire confidence faster than unclear expectations and a chaotic first day. When employees don't understand what success looks like or what they're supposed to be doing, they feel lost and unproductive.
Clarifying Deliverables and Success Metrics
Role clarity is fundamental to employee engagement and performance. New hires need to understand not just what they'll be doing, but how their success will be measured and what impact they're expected to make.
Vague job descriptions and unclear expectations contribute to 23% of employee turnover within the first year. Clear role definition, on the other hand, increases job satisfaction by 2.5x and improves performance by 25%.
Essential Clarity Components:
Specific job responsibilities and daily tasks
Performance metrics and success indicators
30-60-90 day goals and milestones
Decision-making authority and boundaries
Key relationships and collaboration requirements
What a "Great First Week" Should Look Like for New Hires:
A well-planned first week creates momentum and builds confidence. Every activity should have a purpose and contribute to the new hire's understanding of their role and the organization.
Day 1 Structure:
Welcome meeting with direct manager (30 minutes)
Office/workspace tour and introductions
Technology setup and system access
Lunch with team or buddy
End-of-day check-in
Week 1 Milestones:
Complete all administrative requirements
Meet key team members and stakeholders
Understand company culture and values
Set up workspace and access essential tools
Establish communication preferences and meeting schedules
Technical onboarding gets most of the attention, but social onboarding often determines whether new employees thrive or leave. Without meaningful connections, even the most qualified new hires struggle to integrate and perform effectively.
Do Workplace Relationships Affect Onboarding?
Workplace relationships are fundamental to employee engagement and performance. Employees with strong workplace friendships are 7x more likely to be engaged and show 50% higher retention rates.
Social isolation, especially in remote and hybrid environments, leads to decreased motivation, reduced collaboration, and higher turnover. New employees who don't form connections within their first 90 days are 3x more likely to leave within the first year.
Benefits of Strong Social Onboarding:
Faster integration into team dynamics
Improved knowledge sharing and collaboration
Reduced anxiety and increased confidence
Better understanding of company culture
Higher job satisfaction and engagement
Best Practices for Buddy Programs (Remote & In-Person)
A well-designed onboarding buddy program provides new hires with a go-to person for questions, cultural guidance, and social connection. The key is selecting the right buddies and providing them with proper training and support.
Buddy Selection Criteria:
Strong performers with positive attitudes
Good communication and interpersonal skills
Available and willing to invest time
Representative of company culture and values
Different from direct manager to provide alternative perspective
Buddy Program Structure:
Week 1: Daily check-ins and immediate support
Week 2-4: 3x weekly scheduled conversations
Month 2-3: Weekly coffee chats or informal meetings
Ongoing: Available for questions and guidance
Remote Buddy Best Practices:
Video coffee chats and virtual lunch meetings
Screen sharing sessions for tool training
Slack or Teams channels for quick questions
Virtual team activities and social events
Regular feedback collection from both parties
Mistake #5 – Lack of Ongoing Check-ins and Feedback Loops
The most dangerous onboarding mistake is assuming the process ends after the first week or month. Without ongoing check-ins and feedback loops, small issues become big problems, and new hires drift away before anyone notices they're struggling.
How Long Should Employee Onboarding Be?
An effective onboarding is continuous a process that shouldn't end within the first week. Research shows that it takes an average of 8 months for new employees to reach full productivity, yet most onboarding programs last only a few days or weeks.
Extended onboarding programs that last 90 days or more result in 50% higher retention rates and 62% higher productivity scores. The key is maintaining engagement and support throughout the critical first quarter.
Extended Onboarding Timeline:
Days 1-7: Intensive support and basic integration
Weeks 2-4: Skill building and relationship development
Month 2: Project ownership and independence building
Regular feedback collection allows you to identify and address onboarding issues before they become retention problems. Multiple feedback mechanisms ensure you capture different types of insights and concerns. From employee onboarding surveys to 30-60-90 day reviews, there are plenty of ways to receive input from your new hires.
Feedback Collection Methods:
Daily check-ins (Week 1): Quick temperature checks
Exit feedback (if applicable): Learning from departures
Key Questions to Ask:
"What's going well in your onboarding experience?"
"What obstacles are preventing your success?"
"How supported do you feel by your team and manager?"
"What additional resources or training would be helpful?"
"How likely are you to recommend this company to others?"
Response and Action Planning:
Review feedback within 48 hours
Address urgent issues immediately
Share themes with HR and leadership teams
Adjust onboarding process based on insights
Follow up with new hires on improvements made
