Our Team Firsthand

Dejana Žerađanin

Team Leader

Working at the Callosseum means much more to me than just work - it's an environment with a good atmosphere and team support. It is this positive environment and collegiality that make everyday work more pleasant and motivate you to give your best. During a year of work, I developed not only on a business level, but also on a personal level - I grew along with my position, became more confident in myself and my decisions, and with the help and support of the team and superiors, I also developed communication skills. I would recommend Callosseum to everyone who is looking for a stable working environment, an opportunity to learn and develop, but also to work with good people.

Sara Stamenković

Customer Support Agent

I am very satisfied with the people here. As I said, we have a lot of fun with the people here. Even during work and during breaks, we talk to each other, have a lot of fun, meet outside of work, and have a great time then as well.

Balša Raičević

Team Manager

The concept of leadership is very important to me, and in my role as a Team Manager, I believe it's essential to pass that knowledge on to team leaders and experts. What does leadership mean? What does it mean to lead a team? What does it mean to build interpersonal relationships with team members? That's why I consider my role to be very, very important.

You never get bored because every day you get new customers on the phone with different requests, and through that you learn how to adapt to each customer. That way, you can really get a clear picture of things, and if you've been working in this field for a longer time, you can achieve even more.
