Do you get real human respond you immediately when you applied?

Generally not, unless they are interesting in meeting you.

You were probably one of hundreds/thousands to apply.

How did you apply?

But no, normally if they are not interested they just don't reply at all. If they do, it can be months latter,

Employers have a very wide latitude to fill their employment needs, depending on the conditions. Maybe it can take many months to get to your application, if they get to it at all. Likely they have a very long list to work from.
