If you look for a company where you just have to come, sit and do your job, you are definitely not looking at the right company ;)
Hiring more junior roles (great level of energy and fun) can hold some downsides during the transition :
- at times you can find some immature attitudes towards organisational decisions that could be tackled with more time spent taking the time to explain more in depth the bigger picture (recent initiatives are going in the very right direction)
- the lack of people's experience in previous companies leave junior profiles without anything to compare Criteo with, which can sometimes generate impatience in what "fast" really means in terms of promotion cycle. Some tools could be developed to help this population assess more accurately their actual situation in the market
- stress management is still a topic being worked on as I am very confident it will keep helping more our most junior profiles balance their high implication at work through more psychological height and distance
