Not clear what they want to do, except selling plugs.

Pros

Was once a great place to work at, not true any more.

Cons

This company just worries about today. There is no commitment to invest in the future. All they are worried about is to make a quick buck today by selling plugs for data centers. There is no clear direction or commitment to what they want to do in the future except selling plugs for data center buildouts.
