7 Tell‑tale Signs You’re an Inexperienced Programmer (And How to Fix Them)

1. One‑off massive code submissions

Developers who bundle many module changes into a single pull request force reviewers to prioritize their code, create merge conflicts, and delay feedback. The author recommends splitting work into small, daily commits and reviewing each feature separately, possibly via real‑time code review sessions.

Make frequent, small commits—ideally daily.

Avoid submitting code that does not compile or breaks the build.

2. Writing messy code

Inexperienced developers produce tangled code scattered across the repository, making it feel like navigating a maze. Experienced engineers first clarify requirements on paper, draw simple flow diagrams, and only start coding after a solid mental model is formed. Ignoring this leads to painful maintenance and future feature additions.

Understand the feature clearly before coding; ask many questions.

Write clean, elegant code that teammates can read and understand.

3. Working on multiple tasks simultaneously

Novices often start coding immediately without confirming requirements and never communicate progress, only reporting at the end. They also juggle unrelated features, production issues, and help requests, resulting in low‑quality output and wasted team time.

Focus on completing small, well‑defined tasks; break work into bite‑size pieces and prioritize.

Finish one task before picking up the next.

4. Arrogance

Arrogant developers reject criticism, view feedback as personal attacks, and resist constructive suggestions. This attitude hampers professional growth and alienates teammates, whether the developer is a fresh graduate or has a few years of experience.

Stay humble and treat others politely.

Respect every colleague, even when opinions differ.

5. Failing to learn from past mistakes

Effective feedback mechanisms help developers identify blind spots. Inexperienced engineers dismiss all constructive comments, interpreting them as attacks, which signals a lack of real experience.

Maintain a positive attitude toward feedback; decide to accept or reject it calmly.

Learn from errors; continuous learning sustains growth.

6. Handling personal matters during work hours

Some team members browse social media, shop online, or even trade stocks during work, degrading output quality and forcing teammates to work overtime. After a warning, the behavior often returns, sometimes leading to termination.

Avoid personal activities during work; request leave for extended personal matters.

Use breaks or lunch time for non‑work tasks.

7. Blindly chasing tech trends

Inexperienced developers constantly jump to the newest technology, often learning only from tutorials without hands‑on practice. This creates a false sense of mastery and wastes time, while real projects suffer.

Invest time in technologies that are actually useful in projects.

Practice what you learn from tutorials by building functional features.

Hope you can avoid these traps and achieve success in your software career.
