Launched into beta this month by two friends who worked together at Microsoft and Expedia-one of whom also founded Zillow.com--the Sausalito, CA-based site collects real-time reviews, ratings and salary details about specific jobs in specific companies. It operates on a give-and-take philosophy: users can view nearly 32,000 reviews and salary reports for more than 7,000 companies in 80 countries worldwide as long as they anonymously contribute a review and/or salary survey for their current employer or any position they've held within the past three years.

Robert Hohman, co-founder and CEO, says the site "makes it easier for anyone to peek inside the walls of a prospective employer--or even the next cubicle--to get information that will foster more productive conversations and lead to better career decisions."

There are already snapshots of some of the largest multinational corporations and leading commercial real estate brokerages. However, since the site is so new and data is still thin, one review can make or break a company's image. Many ratings are based on less than five reviews, so the data is still statistically unreliable.

Nonetheless, it's interesting to look at trends. For instance, here is what Glassdoor.com is currently reporting on CRE firms:

• Employees at Cushman & Wakefield are apparently happy. Based on the reviews to date, it scores a perfect five in employee satisfaction. One employee notes the firm is "one of the most supportive environments" in which to work, even though "benefits are lower" than they are at competing firms.
• CB Richard Ellis gets a generally positive review--a rating of 4.5 out of five--for its "strong leadership" and "great people." But the current and former employees caution that the firm "is all about building relationships with the client, so one must be patient for things to happen within their career as the client is the primary concern."
• Jones Lang LaSalle is rated 4.3 out of five in employee satisfaction, but earns special mention for its work-life balance and opportunities for advancement. One employee, however, complains about the long hours, the politics of job promotions, "poaching of staff from other firms" and "changing managers means constantly re-proving yourself."
• Grubb & Ellis earns 3.7 out of five, with two employees noting that it features typical corporate American culture.

Users providing feedback are asked to put their views in perspective by listing both pros and cons. The ratings consider a range of factors, including work-life balance, fairness and respect, employee morale, and senior leadership. It also lists salaries for actual positions and titles at specific companies, so users can compare the earnings package at one company to another at a competing firm. It also wants to involve employers through an employer advisory panel, surveys and focus groups.
