Perguntas de entrevista de vagas de Software Development da empresa TechEmpower

Asked some questions about various intricacies of the Java language. ("Why does Java have both Date and Calendar classes", "What is the difference between a Vector, a HashSet, and an ArrayList", "What is the difference between marking a method 'synchronized' and marking a block within a method 'synchronized'", "What does a HashSet do") They wanted to know what kind of programming I was most interested in.
