J'ai postulé via une autre source. Le processus a pris 4 semaines. J'ai passé un entretien chez Oracle (Saint-Pétersbourg, )
Entretien
Got two technical interviews. On the first one I was asked about my experience and projects that I've worked on. Later I was asked a lot of questions about multithreading and security aspects of programming in C. Then I was asked a couple of questions about Java and there were a couple of tasks to find a mistake in a Java code. After that I was given a task to do at home. It required investigation of a platform API and some basic Java threading skills.
Second one was more technical. I was asked about complexity of basic Java collections, some architecture questions like how would you develop a driver or please write a singleton and a couple of logical tasks.
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.
Questions d'entretien [1]
Question 1
Design a highly secure, multi-tenant virtual cloud network block storage migration system that allows live volume transfers between physical data centers without dropping active I/O operations.
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.
Questions d'entretien [1]
Question 1
Something like searching in logs using maps and filter/find data
decent amount of DSA and System design were asked, and behavioral questions. so prepare leetcode level questions and good amount knowledge in sql, java and also mostly oracle sql. overall it was good
