There are two problem-solving approaches:

1) identify a problem that you want to solve, then find a method that will solve it
or
2) pick a method you want to use, and go hunting for problems.

The second way is the stupid way, so it shouldn't surprise anyone that it's the default method in tech.

Continuously refactor your domain model helps to speed up delivery. Get practical tips and lessons in Younรจs Zeriahi's upcoming DDD Europe 2025 talk: buff.ly/MW35dYa

O quizรก el problema son las entrevistas. La IA ya es parte del landscape, no se puede negar. Pero podemos mejorar las entrevistas para detectar mejor habilidades reales de los candidat@s: por ejemplo, pair programming con un problema casi real/รบnico o preguntas enfocadas en experiencia previa.
