Walk me through your ISO career.
I've been in information security for twelve years, six in Oman. Started in IT audit at a Big-4 firm in India, moved into bank-side security, and for the past five years I've been Information Security Officer at an Omani Tier-1 bank. I report to the CISO. My remit: security operations, risk management, compliance, vendor risk, security awareness, incident response leadership. CISSP, CISM, ISO 27001 Lead Auditor certifications.

Tell me about a major security initiative.
Last year I led the bank's compliance with refreshed CBO Cybersecurity Framework requirements: gap analysis across our control environment, remediation programme covering 60+ controls, board reporting on progress, regulatory submission. Twelve months of work. All gaps closed on schedule; regulator-positive feedback at next examination. Major security initiatives succeed on disciplined programme management.
Major delivery.
Describe a major incident.
Suspected phishing campaign targeted bank employees; some credentials potentially compromised. I led the incident response: contained affected accounts immediately, investigated scope, communicated to leadership, notified CBO within regulatory window, supported HR on employee communication. No customer data confirmed exfiltrated. Post-incident: enhanced phishing detection, additional security awareness. Incident response separates mature security functions from immature ones.
Incident leadership.
Tell me about pushing back on a business request.
Business wanted to deploy a new product with security gaps to meet launch date. I pushed back: gaps were material, risk wasn't acceptable. Engaged business sponsor with specific concerns and remediation timeline. Launch delayed two weeks; security included. Security advocacy is part of ISO role; the timing of saying no matters more than the willingness.
Security advocacy.

Technical & role-specific
Questions that test your specific skills for this role.
Walk me through your security framework.
ISO 27001 as the management framework. NIST CSF as the maturity reference. CBO Cybersecurity Framework as the regulatory baseline. PCI DSS for cards. Each framework mapped to controls; controls implemented and tested. Risk register maintained. Regular self-assessment. Annual external assessment. Continuous improvement based on findings. Framework alignment isn't redundant overhead; each framework brings different perspective.
Framework depth.
Describe your risk management approach.
Risk register maintained continuously, not just at year-end. Risks identified through threats, vulnerabilities, business changes. Each risk: probability, impact, mitigation plan, owner, review cadence. Top risks reviewed monthly with leadership. Treatment plans tracked. Risk-aware decision support to business. Risk management is process; ad hoc judgement-based risk-taking is how organisations fail.
Risk methodology.
How do you handle security awareness?
Multi-channel programme: mandatory training annually for all staff, specialised training for high-risk roles, regular phishing simulation, security awareness communication, training for new joiners. Metrics tracked: completion rates, phishing click rates, reported phishing rates. Programme refreshed annually based on threat landscape. Security awareness is the human firewall; investment here pays back disproportionately.
Awareness programme.

Situational
Hypothetical scenarios designed to test your judgement and approach.
CBO requests urgent information about an industry-wide threat. What do you do?
Respond promptly and completely. Investigate our exposure to the threat. Apply any indicators provided. Communicate honestly: we're affected here, not there, our response is this. Regulator partnership during industry threats matters; helpful response builds the credibility for normal-times engagement. Transparent partnership with regulator is a competitive advantage.
Regulator engagement.
Category
Cultural fit & motivation
Why this role, why this company, and how you work with others.
How do you work with business and IT?
Security adds friction; business and IT feel it. I lead with collaboration: understand their goals, design controls that enable securely rather than just blocking. Direct without aggression. Pragmatic about risk; not every theoretical risk is worth the cost of controlling. The relationship matters; security teams seen as enablement get engaged, security teams seen as obstacles get worked around.
Collaborative security.

Closing
The final stretch. Often where deals are won or lost.
What are your salary expectations?
For an Information Security Officer role at an Omani Tier-1 bank I'd target OMR 3,500 to 4,500 total package depending on scope and team size. Roles with significant regulatory engagement pay more. I'd expect annual bonus, certification budget, and equity-equivalent. I'm on 90 days' notice. Beyond pay I'd value the CISO function's strategic positioning; banks with strong CISO voice produce different work environments.
Range and culture preference.
