A bad IT hire costs companies between $50,000 and $240,000 when you factor in recruiting fees, onboarding, lost productivity, and the eventual replacement search. We’ve seen it happen dozens of times.
Here are the five most common IT hiring mistakes — and how modern skills assessments solve each one.
1. Trusting Certifications Without Testing Application
A CompTIA A+ cert tells you someone studied for a test. It doesn’t tell you whether they can diagnose a real network failure under pressure. We’ve interviewed candidates with four certifications who couldn’t run a basic `netstat` command.
The fix: Test actual command-line skills with real terminal simulations. Certifications can be listed on a resume — terminal performance cannot be faked.
2. Using Generic “Problem-Solving” Assessments
Platforms that test abstract reasoning or generic coding logic miss the point entirely. IT helpdesk work isn’t about algorithms. It’s about knowing that `ipconfig /flushdns` fixes a specific class of issues, or that a slow VPN usually starts with checking the routing table.
The fix: Use IT-specific scenarios that mirror real tickets your team handles every day.
3. Relying on References
References are curated by the candidate. You’re talking to people who agreed to be listed. A 2023 study found that 87% of hiring managers received at least one misleading reference in the past year.
The fix: Objective, AI-scored assessments produce data that’s immune to politics, personal relationships, and selective memory.
4. One-Size-Fits-All Screening
A Senior Network Engineer and a Junior Helpdesk Tech don’t need the same assessment. Testing your senior candidates on password resets wastes everyone’s time. Testing your juniors on BGP routing will discourage good candidates unnecessarily.
The fix: Match assessment difficulty to the role. Use Junior/Mid/Senior/Expert difficulty levels with role-specific scenarios.
5. Slow Screening Kills Your Pipeline
The best IT candidates are off the market in 10 days. A multi-round phone screen process that takes three weeks loses top talent to competitors who move faster.
The fix: Async assessments that candidates complete in 15-30 minutes on their own schedule. You get results the same day. Interview only the people worth interviewing.
