Had anyone here done formation.dev? What are your impressions and takeaways?

I strongly recommend just pinging people on LinkedIn, no specific people, just ask anyone! I have two responses to this: 1. The main reason the outcomes are so great is because the timeframe is variable and the outcome is fixed. I don't know any program/bootcamp/school that is like this, which is why we are our own type of thing. You get the result you want and you get there on your own timeline rather than working on someone else's fixed timeline and getting whatever result you can get. All of the logistics I've already described are 100% accurate and talking to people should confirm that (if it didn't let me know and I will reword something) 2. Our team is legitimately experienced and senior compared to anything else out there. We have 3 ex-principal FB engineers (E7+), we have 3 more ex-senior FB/FAANG engineers (\~8 yrs each) who have done many hundreds of interviews each (Amazon Bar Raisers, interviewer creators/trainers, etc...) . We have a ex-FB 10 year recruiter who ran the internship program, and 2 more \~5 year FAANG recruiters. We have a head of career services who is a negotiation expert. We pay are our employees well and myself and Sophie take $0 salary and have made $0 from Formation, so that we can hire the best people possible. EDIT: we have dozens of senior/staff/principal/director level mentors (who are not on staff) and you work with a few different ones intimately every week. People often tell me they didn't believe the mentors would be so senior. This might sound a bit jerky, but I was extremely successful at FB. I started in 2009, was there for 8 years, was promoted very quickly and received a lot of stock. I have no financial incentive to do Formation at all and it's purely out of a mission to get more nontraditional and under-presented engineers into top tier roles and increase the diversity on these teams. It's a true mission and that's why I try so hard.
