How to Screen IT Help Desk Technicians: 8 Questions and What to Listen For Screening Interview Template

Describe your IT support experience. What level of support have you provided (tier 1, tier 2, tier 3), and what was the size of the user base you supported?

What this assesses: Establishes experience level and scale of support operations the candidate is accustomed to. Strong answers are specific: tier level, user count, environment (MSP with many clients versus one internal user base), and daily ticket volume. Weak answers inflate tier level or describe informal 'I was the person people asked about computers' experience, which rarely survives a real queue with SLAs. Someone who supported 50 users part-time is a different placement than someone who worked a 2,000-seat environment.

Walk me through how you would troubleshoot a user who reports their computer is running very slowly. What steps would you take?

What this assesses: Tests systematic troubleshooting methodology, the core skill of the job. Strong answers start with questions (when did it start, one app or everything, any recent changes) before touching anything, then move through a logical sequence: check resource usage, startup programs, disk space, updates, malware. Weak answers jump straight to 'reboot it' or 'reimage it,' recite steps with no diagnostic reasoning behind them, or never ask the user a single question, which signals a tech who closes tickets without fixing root causes.

What ticketing systems have you used (ServiceNow, Zendesk, Jira Service Desk, Freshdesk)? How do you prioritize and manage your ticket queue?

What this assesses: Assesses familiarity with common ITSM tools and, more importantly, queue discipline. Strong answers name specific systems and describe a real prioritization logic: severity and user impact first, SLA clocks, escalating what is beyond them instead of letting it age. Listen for whether they document as they go; sparse ticket notes are a top complaint about junior techs. Weak answers cannot name a system, prioritize purely first-in-first-out, or treat documentation as something they do 'when there is time.'

What operating systems, networking concepts, and hardware are you most experienced with? Do you hold any IT certifications (CompTIA A+, Network+, ITIL, etc.)?

What this assesses: Evaluates technical breadth and verifies certifications for placement matching. Strong answers map their depth honestly: solid on Windows and Active Directory, lighter on Mac, comfortable with DNS and DHCP basics, and they state cert names and dates. Weak answers claim everything at expert level or hide behind the cert itself; a candidate who holds an A+ but cannot explain what DNS does in plain terms memorized the exam. Weigh certs as a floor, not a ceiling, and probe one claimed area for detail.

Tell me about a time you had to explain a technical issue to someone with no technical background. How did you make it understandable?

What this assesses: Tests the communication half of the job, which drives user satisfaction scores more than technical skill does. Strong answers include a real user and a real translation, an analogy or a stripped-down explanation, plus checking the user actually understood rather than just went quiet. Weak answers are hypothetical, condescending ('I dumb it down'), or skip the empathy entirely. A tech who makes users feel stupid generates complaints no ticket-close rate can offset.

Describe a difficult or unusual technical issue you resolved. What made it challenging and what was your approach?

What this assesses: Reveals technical depth and persistence when the runbook runs out. Strong answers walk through a specific problem, the dead ends, what they researched, and the eventual root cause, including when they escalated and what they handed the next tier. Weak answers describe a routine password reset dressed up as difficult, or cannot recall a single hard problem, which usually means they escalate at the first sign of friction and never build diagnostic muscle.

A caller says they are an executive locked out of their account and needs a password reset immediately. How do you handle it?

What this assesses: Screens for security habits, because the help desk is the single most common social-engineering target in any company. Strong answers verify identity through established procedure before doing anything, regardless of the caller's seniority or urgency, and they can say what verification steps they have actually used. Weak answers prioritize speed ('I'd reset it and follow up after') or defer to authority pressure. A tech who fails this question is a breach vector, not a hire, no matter how strong the rest of the screen is.

Are you available for on-call or after-hours support? What is your preferred work arrangement (on-site, remote, hybrid), and what are your pay expectations?

What this assesses: Captures the placement logistics that most often break help desk hires. Strong answers are concrete: which shifts and on-call rotations they will take, whether they can be on-site when a hands-on ticket demands it, and a realistic pay range for the market. Weak answers promise total flexibility that collapses when the first weekend rotation lands, or hold remote-only expectations for a role that requires desk-side visits.
