Opening & warm-up
How interviewers test your communication and preparation right from the start.
Walk me through your security consulting career.
I've been in security consulting for eight years, three in Oman. Started in Big-4 cybersecurity practice in India, moved into bank-side roles, and for the past three years I've been IT security consultant at an Omani Tier-1 bank's CISO function. My remit: advisory across business and IT projects on security design, risk assessment, security architecture input. CISSP and CISM certified. I bridge security policy with project execution.

Behavioural (STAR)
Past-experience questions. Use the STAR framework: Situation, Task, Action, Result.
Tell me about a major engagement.
Last year I supported the bank's open banking initiative: security architecture review, threat modelling on the API platform, identity and authorisation design, regulatory compliance mapping. Twelve months of advisory work. Initiative launched with strong security posture. Open banking creates new attack surface; getting security right during design is far cheaper than retrofitting.
Engagement delivery.
Describe a risk assessment you led.
Annual risk assessment for our cards platform: threat modelling, vulnerability analysis, control evaluation, residual risk calculation. Identified two high-risk areas requiring board-level attention. Remediation programmes followed. Risk assessment done well is rigorous and decision-supporting; done badly is theatre.
Risk methodology.
Tell me about a difficult security recommendation.
Project team wanted to use a third-party authentication service with weak attestation. I recommended against; risk wasn't acceptable for our context. Project sponsor pushed back on the timeline impact of finding alternative. Worked with him on options: pilot service with enhanced controls, alternative service with proper attestation, or in-house build. Alternative service chosen; launch delayed one month but with appropriate security. The harder conversation upfront is easier than the breach conversation later.
Security advocacy.

Technical & role-specific
Questions that test your specific skills for this role.
Walk me through your threat modelling.
STRIDE-based: Spoofing, Tampering, Repudiation, Information disclosure, DoS, Elevation of privilege. Per component and per data flow. Threats prioritised by exploitability and impact. Mitigations designed per threat. Documented for project records. Reviewed against actual implementation. Threat modelling at design saves controls that are expensive to add later.
Threat modelling depth.
Describe your secure SDLC.
Security in design phase: requirements, threat modelling, security architecture review. Security in build: secure coding standards, SAST, dependency scanning. Security in test: DAST, penetration testing for higher-risk releases. Security in operation: vulnerability management, incident response. Each gate has criteria. Security shifted left reduces cost and risk vs security at the end.
SDLC discipline.
How do you handle third-party risk?
Risk-based: vendor's data access and criticality drive assessment depth. Standard questionnaire plus evidence collection (SOC 2, ISO 27001 certs, pen test summaries). Contract requirements: audit rights, breach notification, security obligations. Ongoing monitoring. Risk-rated vendors with proportionate attention. Third-party risk often becomes our risk; rigour matters.
Third-party depth.

Situational
Hypothetical scenarios designed to test your judgement and approach.
A pen test finds a critical vulnerability in production. What do you do?
Engage emergency response immediately. Assess severity and exploitability. Compensating controls in the meantime if patch isn't ready. Patch on accelerated timeline. Communicate to relevant stakeholders and regulator if disclosure required. Post-incident review on how the vulnerability got into production and what process change prevents recurrence. Pen test findings are gifts; act on them with appropriate urgency.
Vulnerability response.

Cultural fit & motivation
Why this role, why this company, and how you work with others.
How do you work with project teams?
Project teams want delivery; security can feel like a brake. I engage early, not late. I explain why specific controls matter, not just what they are. I propose secure designs, not just reject insecure ones. I'm responsive: questions answered fast, reviews completed on schedule. Project teams that trust security engage them; project teams that distrust security work around them.
Collaboration.

Closing
The final stretch. Often where deals are won or lost.
What are your salary expectations?
For a senior IT security consultant role at an Omani Tier-1 bank I'd target OMR 2,200 to 2,800 total package depending on scope and project portfolio. Roles with significant regulatory or transformation advisory pay more. I'd expect annual bonus and certification budget. I'm on 60-90 days' notice. Beyond pay I'd value the CISO function's strategic engagement.
