Red flags
- Talks down to non-technical users
- Skips identity verification for convenience
- Jumps to reinstalling or reimaging without diagnosing
- Does not document tickets or solutions
Questions not to ask
- Can you lift 50 pounds? — only ask about lifting if it is an essential function, and ask whether they can perform it with or without accommodation
- Do you have a car and kids at home? — family status questions create discrimination risk; ask only about availability for the stated schedule
- Have you ever been arrested? — arrest records can create disparate impact claims and many states and cities restrict criminal history questions
- What is your native language? — national origin discrimination risk; ask only about languages required for the job

Frequently asked questions
What are the best interview questions to test IT troubleshooting skills?
Scenario questions like 'a user cannot connect to Wi-Fi' work well because you can hear the candidate's order of steps. Strong candidates ask clarifying questions and check scope before trying fixes.
Should an IT support job description require certifications?
Certifications like CompTIA A+ can be useful signals, but hands-on experience often matters more. Listing them as preferred keeps the door open to strong candidates without them.
How do I test customer service skills for an IT support role?
Role-play a short call with a frustrated user and watch how the candidate listens, explains, and sets expectations. Behavioral questions about past difficult users also reveal patience and tone.
