I don't know what BFS is. I just googled it. Oh, I know what it is now. If you haven't been exposed to it, it's just jargon. That's the point. You are testing for jargon rather than ability. It is the distinction between saying 'implement FizzBuzz' and going silent, and actually explaining what it is. As an interviewer it is easy to forget that whilst you may have asked a question 20 times, this may be the candidate'…
Trees and graphs are fundamental to computer science and there are only two ways to traverse them. I don't know what kids are doing these days, but I learned this because of my high-school curricula. In other words, it's OK if you don't have a formal education in computer science, but when you don't have it, you need to make up for it by learning on your own, because this is basic stuff that high-school kids are lear…
The article might go over the top a bit with self-pity, but personally I just see it as suboptimal behaviour.

I think fundamentally the idea of paying developer X 40K and developer Y 80K (because developer Y has been twice as effective in the past) is broken, because it negates the impact of environment.
If you pay someone 150K GBP in London they can live next door to the office, have TaskRabbit like services perform all household tasks for them, and spend their time exercising and reading 24/7. They will kill it.
Pay them 30K, and regardless of pedigree, they're going to struggle.
Somewhere in there is a balance and I argue it's far less to do with certification and more the circumstances of life which as an employer you have huge discretion to influence.
Basically, it's about steelmanning. Why is someone bad? Is it that they're inherently genetically dysfunctional? Or is it that they haven't been coached well or have a difficult environment?
Given good faith, most of the developers I know have the ability to be amazing. I include myself in that (am I that good? dunno, impostor syndrome innit). But they are stifled by needless nonsense. Management, open office, low pay, commute, stress, basically. Kill the stress and you get your '10x engineer'. Keep the stress and your '10x engineer' turns into a chocolate mousse.
