size attribute requires string parsing.

[rwe]

The company size attribute (size) is currently specified to have a string "10-50". In order to get minimum and maximum company size, that string must be split and parsed which seems unreasonable for a machine-readable spec.

Suggest something like:

"companySize": {
    "min": 10,
    "max": 50,
}

Or possible "from" and "to", if it should be consistent with other attributes.

I was thinking about it. You don't really need to know exact number and it changes a lot. Ideally, you want is an enum. I'll look into json schema enums.
