TIP No. 2:
KNOW THE JOB DESCRIPTION WELL AND KEEP YOUR ANSWER RELEVANT TO IT.
Know the job description and the detailsof what the employer is looking for! Then, talk about your experience and education that fits directly into that job.
It sounds straightforward, but MANY people do not do this. It seems like they sit down for their interview and honestly have no idea what the job entails.
Some people spend half their time wondering all over the place and only once in a while hitting on information the hiring team really wants to hear.
YOU WANT TO BE IRRESISTIBLE: To be the person that has finally come to fill a void or solve their problems, or get them back in the swing of things.
If you read in the job description that the employer is looking for someone with skills in a specific software or function, please provide the details. Don’t just say, “I’ve worked with that software.” How? For how long? How well do you know it? Do you have a brief example of a project you did with it?
“I am a supervisor.” Of who or what positions? For how long? How many people? What kind of work do you direct? What challenges did you face?
Give a full and clear picture of your past experience.
If you have a job or two in your past that you really can’t find relevant experience in, please mention them, but don’t go into the minute details. It’s not related. In fact, sharing too much unrelated information in an interview typically accomplishes the opposite of what you want:
1) it makes the interviewer start to think, “maybe this person doesn’t have what we’re looking for,” or
2) it makes the interviewer say, “this candidate is so long-winded and does not know how to be succinct and organized.”
