Glassdoor, the site where employees can rate their employers, released its Top 25 Companies for Culture & Values today. While the honorees aren't exactly young startups, at least one of them was in your shoes not too long ago. 

Twitter, founded in 2006, came in at number one on the list. The rankings were determined by company reviews submitted on Glassdoor over the past year. Edelman and Google took the number two and three spots, respectively.

Google, which recently celebrated its 10th IPO anniversary, is a prime example of how important it is to define your company culture early on, since this can shape the work environment for years to come.  

For example, in Google's S-1 form, founders Larry Page and Sergey Brin stated that they would focus primarily on big picture goals rather than get distracted by short-term trends.

Now, 10 years later, this idea has surfaced in the words of one of their current employees. "The idealism is also reflected in the projects that get funded: not so many projects that chase the gimmick-of-the-day; more projects that lay out a vision of a better world," a Cambridge-based Google software engineer wrote on Glassdoor. 

And what does Twitter offer its employees in the way of company culture? Well, rooftop meetings for one, according to a San Francisco employee. But transparency, as well, Twitter CEO Dick Costolo told the audience at the National Venture Capital Association meeting last year. 

"One thing I try to impress on all managers is that they make sure everyone on their team understands what they understand. When that happens, office politics kind of drift away," he said.  

To view the other companies that are doing company culture right, according to their employees, take a look at the graphic below.
