Preguntas de entrevista para el cargo de Analyst Programmer II/Web Developer en Feynman Group

The first interview was actually a first and second interview; I first had an interview with the CEO (!), reportedly for team fit, then a day or two later with two of the technical team leads. Somewhat informal. Technical interview was not overly in depth. I believe I lost points, or possibly lost out entirely, for fumbling over the quoted question (from the technical interview).
