It baffles me that AWS, a leader in cloud computing can make such a rudimentary mistake. Seriously, I interviewed there and they asked me to write a b+ tree and I failed. And then you see fundamental errors like this which possibly cannot be made by people who had the smarts to write b+ trees in 15 minutes... I want to take this opportunity to complain about the interview system. Hire people who care about the produc…

This is unquestionably an H1B's fuck up.

Writing a B+ tree from memory and making sure your infrastructure isn't doing something stupid are fundamentally different skills. One requires that you regurgitate the contents of a text book on a white board, the other that you can engineer a solution. I wish them well on an interview set up for hiring the former; I try to hire the later.

I doubt whether tech companies have data to backup for this type of interview, something like the correlation between people who do well in whiteboard binary inversion interview and people who do well in real world jobs. Or they just do it because that's the way Google does it.

Writing B+ trees at the drop of a hat is probably more a signal of memorization and recency of taking a data structures class than smarts, particularly the smarts necessary to develop and maintain robust distributed infrastructure.

This is a problem of "monoculture" dependencies and failure to implement HA by using multiple services. All Github releases are down, atom downloads are down and so on. Companies, including Amazon, should be using other CDNs for HA purposes, even if NIH. It's a similar mistake of making DNS a dependency for monitoring/control infrastructure when DNS is down.

Assuming that it actually makes business sense to do so. There are certainly cases where you can make a perfectly rational business decision to depend on someone else's services and you're OK with your uptime not being any better than their uptime.

It's funny. You know it. I know it. Entire HN knows it. And yet _no_ interview follows any such common sense rules. Just go to a Google/FB interview and they ask you all sort of questions. It doesn't matter what you are interviewing for. In fact, in many cases they don't even tell you which group/team/project you will be assigned to. Since they will "assess" where you fit best.
