The most important factors to consider when searching for a job -- work-life balance, culture, a company's financial health -- are also the hardest to gauge from a candidate's perspective. Or at least they used to be.\nCareerLabs, a new job search site that launched last week, uses machine learning and big data analytics to give job seekers an insider's view of their potential employers and helps them avoid making a career mistake.\n"The things that matter the most for candidates are usually the hardest things to get accurate data on. That's why we created CareerLabs. We have hundreds of millions of data points at our fingertips, and we wanted to use them to give job seekers an unbiased, unvarnished real-time view of companies before they click 'Send' on an application," says CareerLabs co-founder Anthony Van Horne.\nA recent study from Hudson Research revealed that work-life balance is the top priority for job seekers, but it's also almost impossible to get a sense of how a company approaches that through a traditional job listing. Even sites like Glassdoor and Indeed, though they include anonymous, objective reviews, fall short in places, Van Horne says.\n[ Related Story: How to reverse-engineer finding elite tech talent ]\nExpanded filters\nCareerLabs includes job search filters like work-life balance, culture, political affiliation of senior management, the financial health of a company and more, says Van Horne, which allows job seekers to get an inside look at a firm to decide if it's truly a good fit, or if it just looks that way on paper. The depth and breadth of objective information is why Van Horne likes to refer to CareerLabs as "the Carfax of job search."\nThe site uses machine learning technology and data analytics to parse information from more than 22 million U.S. companies and more than 20 million aggregated job listings. The data is culled from publicly available information and from input given by business's current employees to form comprehensive company profiles that include financial health, company culture, management strengths and weaknesses, work-life balance, political affiliations, career progression and advancement opportunities, compensation and benefits and job satisfaction, among others.\n[ Related Story: Want better IT talent?

After the 2008 economic crash, his position at Goldman-Sachs felt shaky, but he and his friends and colleagues found available job-search sites inadequate.\n"In 2009, it wasn't just about people asking, 'can I find another job?' it was about, 'How long will that job last if I go work somewhere else?' That's what no job search site could tell us -- things like a company's financial stability. Sometimes, a job search is a commitment of 12 months or more, and we felt having more information like this could make the difference between finding a company you could stay at for the rest of your career and one that would have you back out in the market a year later," Van Horne says.\nThough much of the information aggregated is free and publicly available, CareerLabs attempts to provide it an easy-to-consume format, Van Horne says, and offers it for companies of all sizes, even less well-known firms.\n"We wanted to this be like a shopping experience, so it's modeled somewhat after consumer retail practices. Yes, much of this information is free and publicly available already, but it can be difficult for the average candidate to go find it. Not only that, many times this information's harder to find for smaller companies that might be a fantastic fit for a candidate, but the firm doesn't have the same name brand and it's harder to find," he says.\nIn CareerLabs' testing phase, Van Horne says the site's most popular filter has been Employee Morale, and the capability to search for companies with remote work opportunities has really resonated with millennial candidates.\n[ Related Story: How recruiting software firms help close the diversity gap ]\n\nBenefits for businesses\n\nCareerLabs has a team of data scientists continually aggregating data and identifying trends like this, he says, which will help companies looking to add or subtract benefits to better attract talent. He says that many companies have benefitted from social and etiquette norms that discourage candidates from asking about perks and benefits like vacation, work-life balance, parental leave, bonuses and the like.\n"The things that potential employees want to know about are the very things they're told they shouldn't ask about in a job interview. Until now, there's been no incentive for companies to change in response to job-seeker demands. In this tight talent market, though, with our tool, companies are going to find that unless they focus on what their talent wants, they're going to lose out to competitors," he says.
