"How are you?" - do u really mean it?

When oz asks how are you, hows your weekend etc, do you guys really mean it to know the information?

Or is it equivalent to "Hello" or "Hi"?

Many times especially in the office settings, people asked how are you going or hows your weekend, it's like they're saying hello. The reason because usually when I started giving the information, they quickly divert the conversation like oh btw dont forget to work on that or this etc...

Therefore most times I dont even bother telling anything more than 1 word like "Good" or "Not bad"...
