What skills should I work on as a computer science student to prepare myself for roles and interviews at Nokia?

Hi!
My advice is to focus on reading Nokia's job offers in order to identify key areas of expertise, for example: software engineering, REST APIs, Java.
Since Computer Science is broad, it's worth to select your path which will be aligned with the role.
You can focus on developing strong programming skills (language depends on the role, e.g. C++, Java, Python), learn data structures and algorithms, and build relevant knowledge in areas like telecommunications, cloud computing, or cybersecurity based on the specific job requirements.

Good luck during the interviews!
