Interview
Al final tanto rollo para luego no hacerte la entrevista técnica. La verdad es que no merece la pena perder el tiempo ahí, da igual lo que realmente sepas de programación
Interview questions [1]
Question 1
Cosas del estilo de tecnologías que había utilizado, experiencia laboral, educación y certificaciones, en qué proyectos había colaborado o contribuido, etc.
I applied online. I interviewed at T-Systems in Jan 2024
Interview
Recruiter call > technical interview > manager interview > offer
Technical interview covered core Java concepts (data structures, garbage collection, concurrency, inheritance, design patterns...), live medium level leetcode problem, easy SQL question.
Many of the questions seemed like trivia instead of testing actual working knowledge with Java, eg. which path would you import package 'x' from? Name all the methods in the Object class. Interviewer was rude when I didn't know the answer to some questions.
