Questions posées lors d’un entretien d’embauche pour Software Engineer - Java Developer chez Saint-Gobain

There are two rounds as mentioned but actually it's three. Two technical and one hr. It's slow process. They are developing in house projects. My technical panel was sitted in front of laptop and asked questions to me. Requirement is for spring and hibernate but he asked me single questions on it and more on core Java. I do not think so he is professional and technical because he asked me basic questions and asked me this class came in which version of jdk etc. That's my personal opinion. Wasted whole day as I already told them that I have my office and have to attend anyhow. On this contract i agreed to scheduled but ☹️☹️☹️
