How long have you been working for the dataglobal Group?

The ITIL service management processes and roles form the basis for our services.

We deliver all phases of the managed service from conception, takeover/transition, operation to the return of the services.

How do you guarantee the security and compliance of managed services?

In the two very important areas of security and compliance, we plan, manage and monitor the following measures on an ongoing basis:

Pia Studzinski (Trainee in Sales)

How long have you been working for the dataglobal Group?

Since 01.01.2024

What are your daily tasks and what do you focus on in your training?

I go through several departments in my training, but my focus is on Inside Sales. This includes the following activities:

  • Order processing
  • Quotation preparation
  • Audit
  • Processing e-mails
  • Working with SalesForce (CRM) and Site (ERP)
  • Amendment contracts
  • Process notices of termination and record them in the systems
  • Telephone reception

As I’ve only been in Sales so far, I can’t say anything about the other departments yet.

What do you particularly like about Sales at the dg Group?

I really enjoy customer contact and order processing.

I never thought I’d say this, but I’m particularly excited about the connection to math! I enjoy applying the things I learned at school and calculating amounts. I do this, for example, when creating maintenance tickets, the difference between maintenance and subscription and when entering an order in our “SITE” (ERP) system.

What is particularly important to you in training? Can the dg Group fulfill these requirements so far?

A trainee should be well received and also be allowed to take on responsibility. After just a short time, I was allowed to help out a lot and take on responsibility and, thanks to my nice colleagues and my trainer, I have fun at work every day – and you can even have breakfast or a snack in between! 😊

At the dataglobal Group, I also like the fact that I was immediately welcomed into the “family” and was even invited to the annual Christmas party before I started my apprenticeship.

I also find team building and communication very important, which the dg Group fully fulfills. I really like the fact that there are weekly meetings to clarify situations for everyone in the department and to discuss everything.

About once a month, there is also a meeting with all employees and the management to discuss a monthly review. There’s always something delicious to eat here too – and you can win me over with food anyway!😄

“A trainee should be well received and also be allowed to take on responsibility.”

Where do you see our goals in Sales? What challenges do we face?

A major goal at the moment is to convert as many customers as possible to subscription contracts, which of course poses challenges from time to time. We have to make a good case here and explain the benefits.

Another major goal is to analyze the monthly data in order to recognize how useful a campaign is, for example, and to react to it with changes if necessary.

How is the cooperation with colleagues and the general cooperation in the team and in the Group in general?

Cooperation is very good and everyone keeps an eye on ensuring that no one is put under pressure. If someone has too many tasks, the other person is happy to take on some of them.

How would you describe the corporate culture of the dg Group in your own words?

The dg Group has very nice employees and is an open, modern company.

Would you recommend the dataglobal Group as an employer? Why?

I would definitely recommend the dataglobal Group as a place to train or work. This is because of the points I have already mentioned:

  • Super employee/trainer
  • Modern and open culture
  • Promotes learning (you learn a lot of new things!)
  • Home office offers
  • Lots of communication
  • Delicious food once a month
  • Team events/team building (e.g. our summer party)
  • Flexible working hours
  • Beautiful office furnishings with plants


Thank you very much for the interview, Pia!

The interview series with employees of the dataglobal Group

Lina Dillhardt (Working student in Marketing)

How long have you been working for the dataglobal Group?

I have been working for the dataglobal Group for about a year now, since 01.04.2023.

What are your tasks as a working student in Marketing?

I mainly support the marketing mailings and our social media activities. From time to time, I also create a few presentations and keep our digital filing structure clean and tidy 😉

What excites you most about marketing at the dg Group?

I particularly enjoy the variety of my tasks. I don’t do the same thing every day and have a lot of variety. I’m always learning something new, which not only helps me in my day-to-day work, but also in my studies.

“I’m not “just” seen as a working student, but as a full member of the team and have the same tasks and responsibilities as everyone else.”

What do you think are our most important marketing goals in the near future?

Of course, we want to increase our brand awareness and create a wide reach through social media in particular, but we also want to generate more leads through the webcasts that we hold regularly and advertise in advance.

What do you think is going really well in marketing? What successes have we had in the recent past?

Our marketing department is already doing very well. The fact that we now process everything from a Group perspective makes our work much easier. As we now use a cross-location marketing tool, we can now send mailings to all customers and partners, regardless of the business unit, and no longer have to go to the trouble of creating each mailing several times.

Our social media strategy is also bearing fruit: with our LinkedIn account, we have managed to gain more followers and cracked the 300 mark in the first quarter.

And of course, our first trade fair appearance as the dataglobal Group was also a great success for us. It was a lot of fun and the stand attracted a lot of attention, especially thanks to the great design.

How is the cooperation with colleagues and the general cooperation in the team and in the Group in general?

I work in a great team and the collaboration works very well. In general, I can say that it’s fun to work in a group, because no matter who I need input from, from which department and from which location, I always get feedback quickly. So the collaboration works really well.

How would you describe the corporate culture of the dg Group in your own words?

It’s a bit like a start-up in that a lot of things are being rethought. It’s very relaxed, even though we set ourselves clear goals that we work towards. The flexibility at work makes for a pleasant working atmosphere.

Would you recommend the dataglobal Group as an employer? Why?

In any case!

Richein Bartsch (Software Developer)

How long have you been working for the dataglobal Group?

Five strong years, I’ve been there since January 2019.

What exactly is your area of responsibility?

As a Backend Software Developer, I am currently responsible for working on our dg Cloud platform with our SaaS (Software-as-a-Service) team. I mainly focus on implementing features, bug fixes and improving our backend services (“microservices”/APIs).

Why did you choose the dataglobal Group as an employer? What particularly appeals to you about our products and services?

I chose the dataglobal Group because I have the feeling that the goals are always clear and that everyone in the various teams is working towards a common goal, even if the disciplines do not overlap. I think that in many very large IT companies, this common goal is very blurred between the individual teams. With us, it feels like one big team.

My main interest is the development of the SaaS platform and how we can integrate our existing products into this platform in a technically and commercially viable way.

How do you see the dg Group’s position in the business software market?

Our strength has always been to adapt to changes in the market and in technology, but not too quickly and not too slowly. I think we are very well positioned as we can offer both on-premise and SaaS solutions with our technology stacks.

What is particularly important to you in your job? Can the dg Group fulfill these requirements?

As a tech-savvy person, I like technical challenges and our goals always require solving complex technical problems. Otherwise, of course, it would get boring 😉 Otherwise, I really like the work culture and the flexibility.

How is the cooperation with colleagues and the general cooperation in the team and in the Group in general?

I think it’s great. It’s easy to talk to everyone, and the flexibility of ad hoc discussions and pair programming is very productive when it comes to development.

How would you describe the corporate culture of the dg Group in your own words?

Start-up culture without being a start-up, if that makes sense. Easy going, but serious and determined. The work flexibility is the same. I think it’s a great working atmosphere.

Would you recommend the dataglobal Group as an employer? Why?

In any case!
