3 tips if you ever interview for a civil service job-for both the oral test (which gets you your score to go on the hireing list) and the oral interview for the actual position:
1. always re-read the job description if it is posted at the interview (often they will post it and as you sign-in you will be told "the job description is posted over there please read it and take a seat"-most people just glance at it as they sit down because they have already read it before). read it because it is common to qet a question in the interview that pertains to something in the description (this is to test if applicants follow directions),
2. if given a question with a number of tasks, one of which is "you supervisor has left a message that they need to see you". ALWAYS list that as the first priority (because the supervisor could have information that impacts on every other task and how you will prioritize them),
3. go into detail about any previous jobs tasks or duties, just saying "i was xxxx" does'nt make it. one job title can vary so much from employer to emloyer- a hiring or ranking panel needs to know what you actualy did. they also cannot deter from the written questions to draw more information out (as much as they would like to).
i served on many civil service ranking and hiring panels, i saw many people short change themselves by not telling us enough about their previous work and volunteer job experiences (in large part, people within civil service shot themselves in the foot most often when they took the attitude of "they know what a xxx does-i should'nt have to tell them")-we had to go straight from their answers, we could not assume or draw from our own knowledge of job duties.
