To configure your feed first go to "My feed" page and on the right you will see a floating gear button. Click on it and it will lead you to your configuration page. You can subscribe to keywords, categories and tags. Companies can also be subscribed, but you will have to visit individual company's page and follow them to get it on your feed.
Once you have configured your post, you will get notifications if it matches your configuration settings. For eg, if you subscribed to the keyword "director", any post that contains the word director will be posted to you.
