      Application

      I applied through a recruiter. The process took 2 weeks. I interviewed at NTT DATA (Lima, Lima Region) in Aug 2025

      Interview

      La entrevista fue remota y trató temas como Java, Spring Boot, programación funcional, eventos simples y diagramas de clases. Fue técnica, con buen ambiente y un nivel de dificultad intermedio.

      Interview questions [1]

      Question 1

      ¿Qué es la programación orientada a objetos (OOP) en Java? ¿Qué diferencias hay entre == y .equals() en Java? ¿Qué es una clase interna o anónima en Java? ¿Qué son las expresiones lambda en Java? Da un ejemplo. ¿Qué es una interfaz funcional? ¿Qué paradigmas incorpora Java desde la versión 8? ¿Qué patrones de diseño has utilizado?
