I've started writing a book to give an "inside out" view on the tech interview process. I still remember when I was doing my first interviews, not really knowing what to expect. Then, how I read up what the interview format is like at places like Facebook and different unicorns - going through lots of blog posts, some that contradicted each others.
Right now I'm a hiring manager and I've done hundreds of interviews the past years at large tech companies and startups. And when I talk with people about the interview process, they usually find it fascinating when I explain how recruiters work - and what their motivation is -, why coding itself is not the only thing you want to optimize for, ways people often fail the recruiter screen or how you can (and should) negotiate when you have an offer.
If you had access to a great tech recruiter, a hiring manager, and a technical interviewer, what questions would you ask them? What would you like to know more about, to help more both with your preparation, and your confidence in understanding the process, "behind the scenes"?
