Culture Docs: Facebook, Netflix and Valve

Marton Trencseni - Sat 18 June 2022 • Tagged with culture, facebook, netflix, valve

Many companies have some sort of "Culture Doc", a booklet or similar, which explains to new joiners what the company is about. I received Facebook's "Little Red Booklet" when I joined in 2016 February, and I was amazed how good it was. Recently I was researching other companies' Culture Docs, and found a version of Netflix's and Valve's online. It's interesting to compare and contrast what these different companies choose to put in their Culture Doc. Facebook's Culture Doc is very mission and execution oriented and serious, Netflix is analytical and HR-focused, and Valve's is a lighthearted explanation of how the company works.

"Over 70% of all Porsche vehicles ever built are still on the road today"

Porsche proudly advertises "Over 70% of all Porsche vehicles ever built are still on the road today". Is this a testament of the quality and longevity of Porsche cars, or simply a result of the brand switching from niche sportscar manufacturing to mass production around the year 1999?

Solving 5 algorithmic interview questions

Marton Trencseni - Sat 26 March 2022 • Tagged with interview, python

Recently I was considering whether to introduce some CS style algorithmic interview questions into our Data Science hiring loop, since having an understanding of algorithms and data structures can be useful for Data Scientists. Not having done this soft of interview for a few years I picked up my copy of Daily Coding Problem and starting solving a few problems to refresh my feeling for what it feels like as a candidate, and whether it would give us any useful signals.
