I think you misread my comment, or perhaps our definition of high volumes of code is different. Perhaps junior means something different.

I also suspect what I consider "good communication" you consider "micromanagement".

I like reading and talking about what my colleagues are doing every day. I'm interested. I learn new things, and sometimes I teach others a trick or two. Sometimes I tell them I don't like something and we agree to disagree.

Sometimes the requirements change, and that need to be discussed as well.

Sometimes I just like hearing and sharing stories about things that didn't work out. Yesterday I spend a whole day profiling to try and work out why we are leaking so much memory. I didn't work it out, but I can tell my colleagues what I tried and what I will try next.

The point I was trying to make is that a solid 8 hour work day is a lot of time, and I think everybody should have something interesting to say about what they did.
