Pros
Technological acumen of the company is top notch. Engineering challenges and experience gained are up there with the top of the pack. Some of the engineers are the best in the business and are scary smart. You will be challenged as an engineer and this is a good thing. Very low employee turnaround indicates the Akamai is a very good company to work for. Senior management has trust of the employers to "do the right thing" and are well respected. The feeling within Akamai is that the sky is the limit and the potential of the company is very high.
Cons
Getting up to speed as an engineer takes a very long time as the institutional knowledge held by longtime employees is not well documented. This is further compounded because Akamai's technologies are highly specific and thus highly customized. Having the feeling of being productive can take a long time. The fear of "taking down the internet" makes release cycles very long. This is a valid concern but it permeates every business group and this slows down everything. The company has a hard time sorting through all the potential ideas and prioritizing them. Too many good ideas.
