Blue Ball Technologies Java Developer interview questions

Worst Interview I have ever faced. They are conducting Interviews because they have to keep the record that they conducted the interview so they can show up that to their higher officials . Don't waste your time by attending this useless interview .They will not select you even if you put the best there and Luckily if you got selected they will train you and redirect you to another company and every one knows no one will do it without any benefits. Even if you got tired of attending the interview there, they will call you again to attend the interview in the name of another fake company named PURPLE DATA TECHNOLOGIES .They ask you to visit the same address. Full of fake people, its kind of training Institution with worst infrastructure. I don't ask you to believe me, if you any doubts read google reviews and you can see no one ever had write like " this company is good to work" or "good company for freshers" or "good infrastructure" etc.. etc.. and you can see they will just put in some training in cloud technologies and then redirect you .You may think like I'm giving negative feed back because of I got Rejected.
