Why pre-screen desktop support technicians before the interview
Reimaging fixes almost anything and teaches nobody anything. A technician who reaches for it first will close tickets quickly and see the same problems return, because the cause was a driver, a policy or a failing disk that nobody looked at. The other half of the job is human: the person whose laptop died has a presentation in an hour. A short screen tests diagnosis and composure, which a list of certifications does not.
What actually matters when screening Desktop Support Technician candidates
- 01
Hands-on competence
Check hands-on range: Windows 10/11 imaging via SCCM, Intune or Autopilot, Active Directory account and GPO tasks, Office 365 fixes, printer drivers, laptop RAM and SSD swaps.
- 02
Safety discipline
Probe handling of data protection and physical safety: BitLocker keys, secure disposal of drives, ESD wrist straps, admin credential hygiene, and refusal to bypass MFA on user request.
- 03
Fault finding
Test structured triage: how they isolate a boot loop, profile corruption, VPN failure or slow Outlook, what they check in Event Viewer, and when to escalate to network or server teams.
- 04
Reliability and conduct
Assess ticket discipline in ServiceNow, Jira Service Management or Freshservice: SLA adherence, queue volume per day, documentation quality, and manner with frustrated or senior users.
Pre-screening questions to ask Desktop Support Technician candidates
12 questions grouped by what they test. Ask the same set in every screen and score answers on a consistent scale, or send them as an async video screen and compare answers side by side.
Environments supported
3 questions01What is your experience with the operating systems you have supported?
Listen forReal depth in at least one with the versions and management tooling used, not a list of names.
Equal expertise claimed across every platform, or experience limited to consumer versions.
02Do you have experience with hardware and software installation and upgrades?
Listen forBuilds and upgrades performed at some scale, with a documented standard rather than machine-by-machine setup.
Every machine configured by hand, or no standard build image or configuration.
03Do you have experience supporting virtual machines or remote desktop environments?
Listen forPractical support experience in these environments, including user performance complaints and how they diagnosed the actual cause.
Virtual environments named with no support experience, or performance issues escalated without investigation.
Diagnose before rebuild
3 questions04What strategies do you use to troubleshoot technical problems?
Listen forA method that narrows the cause with evidence, with rebuilding treated as a last resort after diagnosis.
Reimaging as a first response, or fixes applied by trial with the cause never established.
05Can you provide an example of a challenging technical issue you resolved?
Listen forA specific problem with the steps taken and the point their first theory turned out to be wrong.
Problems described that resolved themselves, or no example with an actual diagnosis in it.
06How would you handle a situation where you are unable to resolve a technical issue?
Listen forEscalation at a sensible point with a clear description of what was tried, and the user kept informed.
Keeps trying alone for days, or escalates immediately with no diagnostic work attached.
Priority by impact
3 questions07Do you have experience setting up and managing user accounts and permissions?
Listen forAccess granted by role with a leaver process, and awareness of why permissions should not accumulate.
Permissions granted on request with no review, or accounts left active after people leave.
08How familiar are you with endpoint protection and firewall management?
Listen forPractical experience including a real detection they handled, rather than software installed and forgotten.
Protection disabled to make something work, or alerts never investigated.
09Do you have experience with data backup and recovery processes?
Listen forA restore they actually performed, with awareness of what is not backed up on a typical user machine.
Backups assumed to work, or local user data lost because nobody checked what was covered.
Users under pressure
3 questions10How would you prioritise tickets if several users report issues at the same time?
Listen forPriority by business impact and number affected, applied consistently rather than by who complains loudest.
Tickets handled in arrival order, or priority driven by the seniority of the requester.
11Have you had to explain a complex technical problem to a non-technical person?
Listen forPlain explanation focused on what happens next and when, rather than on what went wrong technically.
Explanations full of jargon, or users made to feel responsible for the fault.
12What is your process for documenting troubleshooting and resolution steps?
Listen forNotes written so the next technician can pick it up, with recurring issues fed back rather than repeatedly fixed.
Tickets closed with one-line notes, or the same problem solved repeatedly with nothing recorded.
How to score responses
Score every candidate on the same four criteria immediately after the screen. At this stage you are shortlisting for panel interviews, not making the final call.
Hands-on competence
35%5Names specific builds, deployment tools and hardware repairs performed, including device counts handled during refresh or migration projects.
Safety discipline
30%5Treats privileged access and end-of-life disk wiping as procedure, citing asset registers, chain of custody and refused social engineering attempts.
Fault finding
20%5Describes a layered process (user, device, network, application) with a real fault traced to root cause rather than repeated reimaging.
Reliability and conduct
15%5Quotes ticket throughput and first-contact resolution rates, writes reusable knowledge base articles, and stays calm with executive escalations.
Reimaging fixes almost anything and teaches nobody anything, so the same fault returns. A one-way video screen asks when they would rebuild a machine.

Process basics
How long should a pre-screening round for this role take?
Ten minutes across eight to ten questions, answered async. At the volumes this role attracts that is far cheaper than phone screening, and it shows how someone explains a technical issue.
How much should certifications count?
As evidence of grounding. They are common and useful. What they do not show is whether someone diagnoses before rebuilding, or how they behave with a user who is already frustrated.
Evaluating answers
What is the strongest signal when screening this role?
What they do when they cannot fix something. Good answers escalate with a clear description of what was tried, and keep the user informed. Anyone who keeps trying alone will hold a ticket open for days.
How do I judge their diagnostic habits?
Ask when they would rebuild a machine. Sound answers treat it as a last resort after the cause is understood. Anyone whose first response is a reimage will keep closing the same ticket every month.
