A pleasant technical interview, without default questions about HashMap, etc. A couple of questions about ClassLoader, design patterns, how Spring Core works from the inside, indexing in relational databases, a small part on system design.
A lot of theoretical questions, some of them really broad like microservices patterns, some specific and basic like how is built HashMap. There was a livecoding part as well in the end. Some problem to manipulate strings and maps
I applied through an employee referral. The process took 1 week. I interviewed at EPAM Systems (Guadalajara, Jalisco) in Apr 2025
Interview
La entrevista fue para Java Developer lo cual me hicieron preguntas relacionado a Java lo cual esta bien, pero el entrevistador se comporto de manera despota, respondia correctamente y no le parecia me seguia preguntando lo mismo, a pesar ya de haber respondido, el audio y video del entrevistador era muy malo y no lograba entender las instrucciones y preguntas del todo, al final de haber respondido algunas preguntas simplemente termino la entrevista sin haber checado demas skills. Al final evaluaron mi experencia en 30 minutos no le intereso nada mas para hacer una evaluacion mas real y justa.
