What makes the Summernaut Internship Program special and different from other programs?

I think it differentiates itself from other programs by its design. The Summernaut Internship Program is designed to connect you with the other participants who are from different backgrounds, such as field of study or geographical backgrounds. Combined with the two rotations, you get a holistic view of the whole company as interns work in nearly every department, and you spend much time together during and after work. This enables you to get a good sense of the company quickly while having a lot of fun!

What three attributes would someone need to succeed in the Summernaut Internship Program?

1. Taking initiative and responsibility – don’t hide behind the others. Speak up when you identity a problem or a potential improvement.
2. Adaptability – you should be able to adapt to new concepts and unexpected situations.
3. Good Attitude – A smile alone won’t get the job done, but a positive outlook and a pleasant disposition – combined with fundamentals such as work ethic and discipline – make for a well-rounded employee.

What was your biggest benefit from the Summernaut Internship Program?

The rotational aspect of the program allowed me to experience different parts of Celonis in a very short period of time. Not only did I get to know interns working in different departments, I also had the chance to learn from senior level employees about their jobs and their purpose in the company. This exposure to all sides of Celonis allowed me to understand which role I wanted to have in the future and prepared me to become a full-time solution engineer at the company.
