CeX Webuy Entertainment Assistant Software Engineer interview questions

Firstly there was an Aptitude test basically consisting of general maths and technical question with 0.5 negative marking. In the technical interview the interviewer was very rude and hes was not having the knowledge about JAVA,DBMS and he was asking the questions on it. Basically they just dont want to hire people if you want to waste your time then you can apply in CEX and they dont know the kind of question that should be asked to an student.
