Preguntas de entrevista para el puesto de Java/J2EE Developer en RAJA

I went to java/j2ee developer position and i reached morning 10.30 am but they called around 2.30pm and only one question asked to me and suddenly rejected and this is not related to technical. very poor they don't know how to manage , worst attitude and i don't know what is the positions and all, i asked to HR but simply you left for the day and rejected. waste of my time. Please don't do like this.
