Want to know about the company before joining!!!

Hi all,
Does any one know any site from where I can get the information about the employer of a particular company? Where I can know about the working culture of a particular company? And what will be the future aspects? If you people know any site so, let me know. Any help from you people will be precious for me.
Thanks in advance for your help.

Hi, it’s really very important and difficult to know about the company before joining. But it helps us a lot when we join the company. I know one site which will give you answer of your questions. Visit pastjob.co.uk/Default.aspx . This link provides information about companies, about employers, working culture and all. All these information are gathered by the previous employees. I hope my information will help you.
Good luck for your future!
