Fortune 500 Companies with Twitter Accounts
A great way to keep tabs on large successful companies who market their employment needs on twitter in real time is to follow the companies directly. One of the twitter accounts managed by HashJobs is @hiring and if you look at the twitter accounts @hiring is following you will see about 180-200 fortune 500 companies with twitter accounts. Feel free to follow them so that you can keep tabs on their hiring needs.
A lot of times these positions are aggregated by other twitter accounts and it takes a while to figure out who exactly is doing the hiring. I find if you follow the companies directly you will save a lot of time.
Below is a sample of big well-known companies sharing jobs on twitter.
