Ball Corporation is the world's largest maker of aluminum beverage cans (Materials sector, Fortune 500 #337; the aerospace arm was divested to BAE Systems in 2024). Public first-person accounts of its hiring loop are unusually sparse for a company its size: the shop-floor and plant-engineering roles that dominate Ball's headcount are filled locally without much online chatter, so almost every search across Reddit, WSO, HN, GeeksforGeeks and TSR came back empty of genuine writeups. What did surface points at a fairly plain plant-hire loop with a short interview and an aptitude/reasoning test.
