Navigating the Challenges of Working with a New Developer
Written on
Chapter 1: The Onboarding Experience
Recently, our team welcomed a new programmer who exuded confidence and appeared well-versed in programming tools and current industry practices. I was optimistic that this addition would enhance our productivity.
However, my initial enthusiasm quickly faded. Upon reviewing the new hire's code, I found myself shaking my head in disbelief. Here’s a breakdown of the issues I encountered:
Monolithic Code Structure
The new developer preferred to consolidate everything into a single file. This approach disregards the advantages of modular programming, which facilitates easier maintenance and better organization. Working with one large file may seem simpler, but it ultimately complicates the management of imports and directory structures, leading to inefficiencies.
Single-Character Variable Naming
The choice to use single-letter variables raised eyebrows. While brevity can be appealing, it often sacrifices clarity. Descriptive variable names, though longer, provide context that aids in understanding the code, whereas single-letter names can confuse both the developer and others who may work with the code later.
Excessive Function Parameters
The principle of "Don't Repeat Yourself" (DRY) is crucial in programming. However, this developer often created functions with numerous parameters, sometimes exceeding twenty. This not only complicates function calls but also makes the code less maintainable.
Large Pull Requests
The developer favored submitting massive pull requests, believing that it would save time. However, this practice can lead to longer review times and increased chances of overlooking critical issues. Smaller, more focused pull requests are generally easier to manage and review.
Neglecting Test Writing
The notion that testing is unnecessary seemed prevalent with this developer. They maintained that their code was flawless and did not see the value in writing tests to ensure functionality. This mindset can lead to significant problems down the line, especially when revisiting code.
Ignoring Test Maintenance
When pressed about the importance of maintaining test integrity, the response was dismissive. The idea that tests should always pass, regardless of their relevance or accuracy, undermines their purpose in the development process.
Withholding Knowledge
There was a clear reluctance to share knowledge or document processes. The belief that keeping information close would secure their position is misguided; collaboration and transparency are fundamental to a productive team environment.
Over-Commenting Code
The developer had a tendency to comment excessively, often more than the code itself. While commenting is essential, overdoing it can clutter the code and detract from its readability.
Avoiding Team Meetings
The developer seemed to have little interest in collaboration, viewing meetings as a waste of time. However, engaging with the team is critical for aligning on project goals and understanding client needs.
Competitive Mindset
This programmer appeared to view their peers as competitors rather than collaborators. Withholding knowledge and refusing to share insights can hinder not only their growth but also the team's overall success.
At this point, I have yet to confront the newcomer directly. I believe it’s prudent to allow management to observe the situation and determine if their hiring decision was indeed a wise one. Perhaps they recognized potential that I have yet to uncover.
Chapter 2: Insights and Reflections
The first video titled "What about a junior dev who acts as a senior?" explores the dynamics of working with junior developers who may overestimate their expertise. It provides valuable insights into recognizing red flags and fostering a healthy team environment.
The second video, "How not to become a senior developer (and what to do instead)," discusses the common pitfalls that can prevent developers from advancing in their careers and offers practical advice on how to avoid them.
