I weren't able to write that code during an interview. I've been asked to scrape unique 200 posts from a json feed.

require 'net/http'
require 'json'

start_url = "https://url-to-json.feed"
posts = []

loop do
  body = JSON.parse(Net::HTTP.get(URI(start_url)))
  next_page = body["paging"]["next"]
  body["data"].each do |new_post| 
    id_exists = posts.detect {|post| post["id"] == new_post["id"] }
    unless id_exists
      posts << new_post
    end
  end
  url = next_page
  if posts.count > 199 
    break
  end
end

Instead of that dumb and simple 15 lines of code, I started to create functions, pipe them each other, do some bullshit abstractions, and finally fucked up.
