3dplm Software Solution Technical Support interview questions

I was called for the interview via a job portal . First round was aptitude and puzzle round . Very less time is given but not so difficult to crack . Then I waited for whole day and then called for technical. It was 1 hour interview in which many use cases where asked related to OS . And then after clearing the round one more telephonic round was there , in which a panel of 4 people where taking interview . The manager was also present and he started asking his level questions despite taking interview for fresher position . I mean they should think once that they are hiring freshers .
