Preguntas de entrevista para el puesto de Java Developer en Frontier Science Foundation

Roughly an hour long in-person interview with three developers. Interviewers were very casual and easy going, overall not too stressful. Questions focus on Java, OOP, and some sql. Had a couple very simple programming questions where you write your answer on a whiteboard. Main challenge was in addressing how they could break my code, how should i handle errors, and such. A few vague conversational questions with a lot of "what if" followups.
