What employees are saying


Consultant (voormalig Young Professional)


Het leukste vind ik de vrijheid die je krijgt om jouw ideale programma samen te stellen. Daarnaast het klantcontact bij verschillende bedrijven, de afwisseling in projecten en de sfeer. Daarom ben ik blij en dankbaar om deel uit te maken van het hardwerkende, maar gezellige team van Slimstock.




Ik ben blij met de afwisseling van mijn functie. Elke dag zijn er andere uitdagingen en puzzels om op te lossen. Ondanks dat het soms haast onmogelijk lijkt om een oplossing te vinden, is er dan uiteindelijk altijd dat eureka moment. Voor mij is dát waar het om draait; uitdaging in mijn werk.
