Researching companies and studying job descriptions are topics that are covered in every presentation on resume writing and interview preparation. Internet access makes finding this information extremely easy. Successful job seeking requires a second type of exploration that is equally important and often more challenging than reading websites: self-reflection.
Every interviewer is trying to determine why they should hire you. Some may ask the question directly, while others will be more subtle. Nevertheless, it is your responsibility to demonstrate to recruiters and hiring managers why the cost of hiring you is a good investment.
