All Data Engineer's Groups consist of "professionals" who talk for hours on end promoting their sponsors. Best case scenarios are that they would have some freebies from their sponsors and promotional from recruiters to desperate job seekers. That's right. It isn't a group designed specifically for data engineers, no no. It's just bull$#*! marketing. I thought I was going to learn something special. Data enthusiasts are talking of working in Japan, building Rasberry Pis or self driving cars and $#*! is better use cases but these morons cannot stop talking. It's literally tiresome. If you are intelligent, just get your ideas from interest groups on the internet and start your own project to showcase your passion. Don't join groups, there's nothing there.
