An interview is an intense and artificial way of measuring whether you will be a good fit for a role. Until another method is developed, it is important to learn how to play this game. My first interview was secured through a friend who had an office suite on the same floor as an Accountant. The interview lasted about half an hour. Part of the interview included the Accountant asking me to write a sentence so he could determine how legible my handwriting was. How interviews have changed!
It should come as no surprise that more and more recruiters are using LinkedIn to search for potential candidates. Firstly it's free rather than having to pay to post on a job board. Recruiters can also search for relevant candidates using keyword searches that relate to the skills they need.
