What is the most significant mistake you see junior developers making over and over again in their work?
They sometimes make things a lot more complex than they usually need to be. There seems to be an assumption that they need to know everything all the time right now—that’s one mistake that I tended to make when I was starting, and I see it a lot now when I work with more junior developers. It’s a hard skill to learn; it takes years of experience and writing to actually recognize that something you’re doing can be done in a much simpler way. But I think the mistake is mainly rooted in trying to do everything all at once.
What suggestions can you give for overcoming this problem?
A lot of it is practice. Also coming back to something you’ve written in the past, because sometimes—especially when we’re on a project—we ship something and then it’s done, right? But I find that if I go back to something that I did even a few months ago, usually there are new ideas that come to me like, “Oh, I could have done it this way rather than that way.” Or the project is actually more simple than I thought. It’s kind of like reviewing past work for a future exam. If you go back and review your code, I think that really helps a lot.
For your learning or growth, do you draw from podcasts or books?
For technical information, usually podcasts. There are a couple that I would recommend to any fellow software developer. The first is the Android Developers Backstage podcast, which is hosted by members of the Android development team. They talk to a lot of Android engineers and people who drive changes and developments in the Android community, so it’s a really good reference as some of the episodes are very highly specific to a topic.
