That doesn't make any sense. Why would someone have interviewed at Google before doing a bootcamp like Lambda School, which is specifically meant to teach someone (with almost zero experience) programming? If you've made it to a Google onsite, you probably don't need to go to a bootcamp.

That is very specific. They have to have made it to an on-site and been rejected before Lambda? Well that eliminates 99% of our student body from contention.

How else can we isolate the effects of the program?

To be honest I subscribe to the idea that the FANG etc interviews are proxies for an IQ test. So it is entirely possible lambda school trains a high enough IQ individual and they pass a full loop. And by that I mean they pass based on their IQ AND the training they got in the program.

If you subscribe to the idea that FAANG interviews are IQ tests, then by definition you won’t be able to isolate the effects of the program. I don’t think we really move the needle on IQ.
