To thrive as a 1st Line IT Support professional, you need a good understanding of basic IT principles, troubleshooting techniques, and customer service, supported by relevant qualifications such as CompTIA A+ or equivalent experience. Familiarity with ticketing systems, Active Directory, Windows and Mac OS, and remote support tools is commonly expected. Strong interpersonal skills, patience, and clear communication are vital for effectively assisting non-technical users. These abilities enable you to swiftly diagnose issues, provide excellent customer support, and maintain smooth IT operations.
