The technologies you work with depend on the company's stack but commonly include languages like Python, Java, or JavaScript, and tools such as Git for version control.

Strong communication, teamwork, and a willingness to learn help you collaborate effectively and adapt to new challenges. These skills and qualities are essential for contributing to projects, growing professionally, and ensuring successful software delivery in a team environment.
