The employee name should contain only alphabets and space and not more than 30 characters on the whole.

1. Field should accept only string.

Create onChange Client Script on that particular field.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }
    var field = g_form.getValue('fieldname');
    if (!field.match(/^[A-Za-z ]*$/)) {
        alert('Please enter only text');
        g_form.clearValue('fieldname');
        return false;
    }
}

2. Limit length to 30 Characters.

Right Click on the field and click on Configure Dictionary and set max length to 30 like below screenshot.
