How interviewers test your communication and preparation right from the start.
Walk me through your senior IT support career.
I've been in IT support for eight years, four in Oman. Started in L1 support, progressed through L2 to senior roles, and for the past three years I've been senior IT support specialist at an Omani enterprise. I cover complex L2/L3 work and mentor junior team members. My remit: incident management, problem investigation, knowledge base development, vendor coordination. Stack: Windows / macOS, Office 365, AD, SCCM, ServiceNow. CompTIA A+, Network+, ITIL Foundation.

Behavioural (STAR)
Past-experience questions. Use the STAR framework: Situation, Task, Action, Result.
Tell me about a major incident you helped resolve.
Office 365 had a major outage for our region affecting email and Teams for 6 hours. I worked the bridge with Microsoft, coordinated internal communications, provided workarounds where possible (alternative communication channels). Documented the incident in detail post-recovery. Senior support's role in major incidents is structured response and communication; junior support handles the volume.
Major incident contribution.
Describe a difficult problem investigation.
Persistent intermittent issue with file shares; users complained about access failures perhaps once a week per user. Investigated patterns over a month: correlation with specific time windows. Eventually identified a backup process locking files during peak business hours. Coordinated with backup team to shift schedule. Issue eliminated. Intermittent issues need patience; quick fixes miss root causes.
Investigation depth.
Tell me about mentoring a junior.
Junior team member was struggling with confidence on complex tickets. I started shadow-pairing: she watched my approach on tough tickets, then I watched hers and gave feedback. Six months later she's handling complex tickets independently and being shadowed by newer juniors. Mentorship is part of senior role; teams don't grow without it.

Technical & role-specific
Questions that test your specific skills for this role.
Walk me through your problem management approach.
Recurring incidents trigger problem investigation. Root cause analysis: gather data, develop hypotheses, test. Permanent fix where possible; workaround when fix has constraints. Problem record documented. Knowledge base updated for similar future incidents. Communication to other support tiers. Problem management is the senior's contribution beyond incident response; volume of incidents reduces over time when problems get addressed.
Problem management methodology.
Describe your endpoint management.
SCCM for Windows, Jamf or similar for macOS. Standard build images. Patch management: critical patches expedited, others on monthly cadence with proper testing. Software deployment via SCCM. Asset management integrated. Compliance reporting. Endpoint security agents managed (antivirus, EDR). Lifecycle management: provisioning, refresh, decommissioning. Endpoint hygiene determines support load.
Endpoint depth.
How do you handle complex AD / Identity issues?
Methodical investigation: replication status, time sync, name resolution, authentication flow. ADUC, replmon, dcdiag for diagnostics. PowerShell for bulk operations. Federation issues investigated with proper toolsets. Permissions reviewed systematically. AD is the foundation of access; understanding it deeply is senior support requirement.
AD expertise.

Situational
Hypothetical scenarios designed to test your judgement and approach.
A user is locked out and frustrated, but security policy requires verification before reset. What do you do?
Follow the verification process; security exists for reason. Communicate to the user empathetically: I understand the frustration, here's what I need to verify identity, here's the timeline. Don't rush past security to please. Most users understand once explained; the few who don't would create bigger issues if security was relaxed. Process exists to protect them as much as the bank.
Process discipline with empathy.
Category
Cultural fit & motivation
Why this role, why this company, and how you work with others.
How do you work with the broader IT team?
Senior IT support is the bridge between users and specialist teams (network, systems, security). I escalate appropriately: not too eagerly (use my own depth first), not too reluctantly (don't become the bottleneck). I learn from specialist teams; cross-pollination of knowledge strengthens the support function. Relationship matters; specialist teams respond faster to support that earns their respect.
Cross-team collaboration.

Closing
The final stretch. Often where deals are won or lost.
What are your salary expectations?
For a senior IT support specialist role at an Omani enterprise I'd target OMR 800 to 1,100 total package depending on scope and team responsibility. Roles with significant problem management or system administration responsibility pay more. I'd value training budget and certification progression. I'm on 30-60 days' notice. Beyond pay I'd value career progression toward systems engineering or other specialist roles.
Range and progression.
