Hi-Tech e Soft Design Engineer interview questions

Firstly i received mail from hi-tech balaji mirkhale. since last two years and not even responded because my many colleagues also get same emails from long time. But recently i went for interview just for gaining interview experience. Firstly when i entered in their office their security guard started interviewing me kitna experience h aur konsa software. After answering he give me a form and after he took me to their tool test pc one person comes and give me a drawing and told me that within 1 hr complete 3d model along with 2d drawing. Drawing with incomplete dimensions!!!! I completed it within time after completion i was shocked with the answer of that person that we will review your cad model and get back to you soon. I ask him what about technical and other interview he answered we call you,,,,, That's all!!!! I am an engineer and they judge only on a 3d model and drawing!!! And if they don't have related vacancies then why they called me. Suck you guys you just wasted my time money and efforts. And finally i dont konw who is balaji. And even no one ready to tell me who is balaji. All this is only non sense plz don't go for interview it all about wasting money time and everything.
