Uber, Culture and Susan J. Fowler

A few weeks ago, Susan J. Fowler wrote about her very strange year at Uber. Basically, she experienced sexual harassment, HR covering up and a poisonous corporate culture. Apart from her personal experience, she characterises the culture like this:

In the background, there was a game-of-thrones political war raging within the ranks of upper management in the infrastructure engineering organization. It seemed like every manager was fighting their peers and attempting to undermine their direct supervisor so that they could have their direct supervisor’s job. No attempts were made by these managers to hide what they were doing: they boasted about it in meetings, told their direct reports about it, and the like.

Hello, I am interviewing people…

Hello, I am Kris (Article about a Twitter meme in english). I was a Database Scalability Engineer at Booking.com.

When interviewing people for my replacement, I have been looking for a “sense of cost” in architectural decision making. I have been giving people rough problem descriptions of what others or I am currently working on, and asked them what they were thinking about the problem.

Since I did not have a solution to the problem yet, my goal was more observing the idea-discovery process and the reasoning about consequences of various approaches in terms of load, toil, network communication and so on, than an actual solution for the problem.

Oh, and I have been a MySQL consultant and database person since 2005, and still google ALTER TABLE syntax.
