Candidatei-me por meio de uma faculdade ou universidade. O processo levou 2 meses. Fui entrevistado pela Oracle (Lausana) em abr. de 2020
Entrevista
I was interviewing with Oracle Labs Zurich. I passed two rounds and interviewers seemed okay. Not without organizational hiccups though: no wonder, the interviewers, recruiter and coordinator sit in three different countries. After that I tried to ping them about the status for about a month (corona time, yeah, I was sick with it myself for two week during that month). Eventually they responded that I was qualified for the next round of selection (no such thing as next round for anyone I know at my school who applied there) and I would have to wait for two months for the update. They referred to corona complications, except that at least two of my classmates got their offers just around the same day I got this response, and they started interviewing process pretty much in parallel with me. Next outright lie was when I asked what was the start date of the internship, and they said that July was absolutely off the table and now I learn that some of my friends start in July. Not to even mention that during the on-campus event I emphasized multiple times that I didn't want to deal with machine learning, and was interested in compilers, and yet the first words from the recruiter were: alright, so you wanna do an internship with an ML team... :)) Overall, I still think they're doing a pretty good job with Graal VM, and there are some super smart people who would be super cool to work with. But the recruitment process is unacceptable.

Entrevista
Se divide en varias etapas, lo primero evalúan tu ingles, ya que es requisito para trabajar ahí, normalmente es solo una entrevista en ingles con preguntas sencillas, como cuál es tu actual trabajo, por qué quieres trabajar en Oracle, y normalmente es alguien de RH, después si pasas esa etapa viene la entrevista técnica en la que te preguntarán conceptos básicos, por ejemplo si es para java te preguntarán sobre herencia, polimorfismo, era entrevista puede ser en español o en ingles dependiendo si es alguien de aquí de México tu manager o si es del extranjero y posteriormente te pondrán problemas de algoritmos que tendrás que programar en el tiempo de la entrevista
1 technical phone screen covering basic networking and data structures, followed by a 4-round onsite loop focused heavily on Oracle Cloud Infrastructure (OCI) scale challenges. The rounds were split between low-level system execution, multi-tenant cloud architecture, and standard relational/non-relational database trade-offs. The interviewers kept drilling into network virtualization, hypervisors, and storage layers.
To prep, I needed to brush up on high-throughput cloud networking patterns and storage engine internals. I utilized Apex Interviewer to simulate full cloud infrastructure design problems.

Mostly coding question focused, and some talking about personal experience and terms. Some technical design, you could have chosen any language to complete the coding questions. Questions were simple technical concepts that person came up with at the moment.
