I highly doubt that's true. It may be what you want in an ideal world, but in reality, very few, if any, companies of this size have any internal ranking system that can accurately identify the 1000 least talented people company-wide. More likely, they're laying off the last 1000 hired if they want to optimize for losing the least institutional knowledge, the first 1000 hired if they want to optimize for immediate labor cost savings, or just laying off all the people that are part of teams working on projects that got scrapped, who happened to be in the wrong place at the wrong time.
