Pros
Great people - smart, with a can do attitude (generally). Ground breaking projects. Cruft has mostly left the company. Below industry average turnover. Flexible work policy, for those that ask.
Cons
Some of the over promoted dead wood remain. They can be spotted with their headphones on all day, Facebook running in a small window, with a bored/moderately pissed look on their faces. Their only remaining contribution to the company being a post to glassdoor or exit interview, both showing a degree of creativity and flair that they had long since forgotten in the workplace. The company has completely transformed the business model in the last 4 years to a fixed price model. At times this is very inflexible and has led to lots of the pain mentioned in other reviews - the company struggled but individuals struggled too. Many of the disgruntled couldn't cope with FP and lots of the whinging in other reviews really hinge on this (unmentioned) point - bluntly, it can be brutal and you are either okay with that or need to leave. Training is poor - this used to be good but HR have been "looking" at this for the last few years and nothing has happened in that time. Vacation is way below industry average and benefits are about average. Generally, all things HR related are poor/reactive. The "Gherkin" - poor office space, very tired, soulless.
