Pros
Opportunity to work in a large project with globally renowned companies. Opportunity to work with the latest technologies like Docker, Hadoop, Spark, Kafka, Elastic Search etc
Cons
For a consultancy that focuses on delivering software solutions to clients, engineers are truely undervalued. The pay is bad. Graduate salary starts at around £26k for all regions (including London...) and pay rises are usually 3%-7% (anything higher than 6% is pretty lucky). There is so much demand for Software Engineers in the market, yet Capgemini keeps their salaries low, even for experienced developers. It is well below market rate which is causing all the good engineers to leave. After leaving Capgemini, I increased my salary by 200% in 2 years, I wouldn't get anything close if i was to stay. Engineers are in high demand right now, you are worth more.
