Today’s newsletter looks different from our usual. It’s a detour to talk about an important topic : career development. Disclaimer: we are not licensed counselors, and are not qualified to give career advice. This is for informational purpose only. We started to build our own proprietary database of job posts from the best tech companies in the world. It’s a lot. Some preliminary data cleaning, and visualizing give us a picture of how product manager differs from program manager, and what do data engineers do all day.
