Pros
No particular pressure to work overtime. Supportive of work from home
Cons
Hierarchical organisation, where strategy decisions are reported from the top, and change moves very slowly. An example of the above is the drive to force off-shoring from low cost centers into doing highly complex work. The work is poor, the communication worse. No one in the rank-and-file likes it, however reporting about it to middle managers has little visible effect. Senior engineers are usually not technically skilled, as they get given all the coordination and resourcing tasks of which there is a lot, so you rely on the scattered few engineers who've resisted getting into management to answer the hard questions, although this seems to be a trend in tier 1 consultancies. Engineers are often moved around between projects frequently, which encourages complacency that someone else will fix mistakes or designs with insufficient detail, although this is an issue with the large contracts Jacobs receives as contracts go for so long.
