What German startups look for

I wanted to know what tech startups in Germany were looking for in their software engineering roles (0-3 yrs experience). To do so, I decided to refer to the LinkedIn Top German Startups lists [1] from 2019-2021. After copying the 'requirements' section of about 100 Software/Backend/Full-stack Engineer job listings from the above startups, I had a text file of 5565 words ready.

The following was the output after running a short Python script for cleaning out English stop-words along with non-skill terms and  printing the 25 most frequent skill terms in the text file:

java      
aws     
python      
spring    
javascript      
docker     
sql

react
