Pros
Very good culture, relaxed enough to be enjoyable while still being aggressive at delivering excellent results. Genuine meritocracy and encouragement to take on interesting projects and grow your knowledge. The fun, casual, focused culture you would expect from a tech company is evident in great measure. If you want to work with people that learn Python and build robot arms in their spare time, this is the place.
Cons
EIG influence post-merger is less ideal. They are fairly tight-fisted with expenses, more aggressive with sales and the bottom line. Corporate culture is becoming more 'standardized' with the merger and it is generally disliked. As an example, insufficient techs on the support floor now have industry standard wait times, rather than Bluehost's prior 'less than 30 seconds' goal. Similar cost cutting is evident in server administrator numbers and compensation as well. This is cheap in the short-run, but expensive in the long run!
