Job seekers can gather a lot of intelligence on prospective employers through Glassdoor, an online site where current and former employees rate hundreds of companies and their CEOs as well as provide guidance on what the job interview process and salaries are like. "Anyone reading the reviews on Glassdoor should keep in mind that the feedback is often negatively skewed because unhappy employees - or terminated employees - are often the ones to voice their opinions," cautions Christine Posti, a Green Tree-based outplacement and human resource consultant.
