Junior Java Developer Interview Questions

"Junior developers are often responsible for writing the more monotonous and simple code required by senior members of the development team. Because of this, interviews will be designed to test your knowledge of the fundamentals of Java so be prepared to answer technical questions that you likely came across in college. Data structures and algorithms will be heavily emphasised. A bachelor's degree or equivalent work experience is required. "
