Microsoft had such a program back in the mid 2000s. It was not heavily advertised but it basically trained people with math/science backgrounds in undergrad. You came in and went to class for half the day and then worked on a product team for half the day over a period of nine months. Just about everyone who came through (being bright already) was able to make it as a high-quality engineer on products around the company. Unfortunately, the program was axed during the Great Recession and hasn't come back.
