I have few friends and colleagues that have recently started working as developers and testers, and I've tried to mentor them a bit. We've talked about what they were struggling with and I've noticed that most of them were under the impression that they were the only ones experiencing a particular problem. From my experience I know this is very unlikely so
I would like to write a post (or few) about the most common problems junior developers are experiencing and for that I need your help and input.

What were the biggest challenges you faced during the first years working as a developer/tester?
Were these mostly technical (e.g. unknown tech stack, in-house framework), social (difficult colleagues, bosses, etc) or was it something else?

If you would like to help, leave a comment below and I hope that will show others that they 're not alone in their struggles.
