DS-MAX Properties Structural Design Engineer interview questions

It was too long and all waste of time with no outcome. Every time they call for interview they waste the whole day and make us sit upto 8.30pm in the night. No response to the person coming for interview and sometimes they call us for interview and cancel it when we reach their office. They take 6 to 7 times minimum to select a candidate. For every interview the CEO takes the two rounds and even after so many rounds they don't even reply something.
