Tell about your biggest failure at work. What did you learn?

One of the biggest failures at work was related to insufficient testing of a new feature, which led to an error in production causing user disruptions.

Conclusions:

• It is important to allocate enough time for testing, including unit, integration, and load testing.
• Do not neglect code review and test automation.
• Quick response and fixing errors are key to minimizing negative consequences.

This experience taught me to approach code quality and testing processes more responsibly.
