My friend is a recruitment consultant and only recruited for vacancies other than IT related roles. He is going for an interview for a position to recruit on an IT desk and needs to know what means what in the IT world (Both hardware and software support).
For example, what are the most commonly used programming languages and for what purpose are they used. And in general terms, what computer specific language is used when identifying certain candidates.
Also, what formal qualifications are needed nowadays to qualify for certain jobs and what would these job titles be?
Ozbargain is the new google apparently.
