I am Jerry Frempong, a UK based career coaching professional with over twenty five years of experience supporting individuals into successful and fulfilling careers. IT Support and Infrastructure remains one of the most stable and opportunity rich sectors in the UK job market. Organisations across public and private sectors rely on resilient technology environments to operate securely and efficiently. This blog post is written to guide you through the full landscape of IT Support and Infrastructure, from graduate entry level roles to board level leadership, including salary expectations, interview processes, and forty carefully structured competency based interview questions and answers using the STAR method. My aim is to motivate and empower you to approach your next interview with clarity, confidence, and professionalism.
Understanding IT Support and Infrastructure
IT Support and Infrastructure refers to the people, processes, and technologies that keep an organisation’s systems operational. This includes user support, hardware, networks, servers, cloud platforms, cybersecurity, data centres, and disaster recovery. Strong infrastructure enables productivity, protects data, and supports strategic growth. Careers in this sector reward problem solving, resilience, and continuous learning, making it ideal for individuals who enjoy both technical challenges and service delivery.
Graduate and Trainee Roles
Graduate and trainee roles are the foundation of an IT Support career. Common job titles include IT Support Analyst, Service Desk Analyst, Junior Infrastructure Engineer, and IT Technician. Responsibilities typically involve logging and resolving incidents, supporting users, setting up devices, and learning core technologies.
Typical UK salary brackets range from twenty two thousand to twenty eight thousand pounds per year. At this stage, employers value attitude, communication skills, and willingness to learn more than deep technical mastery.
Mid Level and Specialist Roles
With experience, professionals progress into roles such as Infrastructure Engineer, Network Engineer, Systems Administrator, Cloud Engineer, or Cyber Security Analyst. Responsibilities expand to system design, upgrades, automation, security controls, and mentoring junior staff.
Salary brackets at this level typically range from thirty five thousand to fifty five thousand pounds per year, depending on specialism and location. London and specialist cloud or security roles often command higher earnings.
Management and Leadership Roles
IT Managers, Infrastructure Managers, and Service Delivery Managers bridge technical operations with business needs. They manage teams, budgets, vendors, and service performance. Strategic planning, stakeholder engagement, and risk management become central.
UK salaries typically range from fifty five thousand to eighty thousand pounds per year. Strong leadership, communication, and commercial awareness are essential.
Senior Leadership and Board Level Roles
At board level, roles include Head of IT, IT Director, and Chief Information Officer. These leaders define technology strategy, governance, investment priorities, and digital transformation. They align IT with organisational objectives and regulatory requirements.
Salary ranges often exceed ninety thousand pounds per year and can reach one hundred and fifty thousand pounds or more in large organisations. Board level success depends on vision, influence, and accountability.
Interview Processes in IT Support and Infrastructure
Telephone interviews are often the first stage. They assess motivation, communication, and basic technical understanding. Speak clearly, smile while talking, and have your CV and notes ready.
Zoom or video interviews test professionalism and presence. Dress smartly, ensure good lighting, and maintain eye contact with the camera.
In person interviews allow deeper technical and behavioural assessment. Arrive early, bring copies of your CV, and demonstrate confidence through posture and body language.
Panel interviews involve multiple interviewers assessing consistency and stakeholder alignment. Address each person and remain calm.
Group interviews assess teamwork and leadership. Listen actively, contribute constructively, and show respect for others.
For all interviews, wear professional business attire. In the UK, this typically means a suit or smart dress, polished shoes, and minimal accessories.
