Vantaggi
People are their greatest asset and they employee a lot of people. As long as you enjoy the people you work with, the company side takes care of itself. Fairly structured on process and procedure, their goals as an organization are well defined (Beyond Zero) and I've experienced the most growth in my career while employed with Jacobs.
Svantaggi
Jacobs is in the business of high volume, low margin. This translates to tight overheads and it shows. Training is infrequent and often gets rebooked by seasons, not days or weeks because there simply isn't enough people available in the overheads to keep up with demand. Jacobs calls themselves a relationship based company and what this means is the client will always be right and get their way, the sooner you accept this fact the better off you'll be.
