I applied through college or university. The process took 1 day. I interviewed at Oracle (Patna, Bihar) in Aug 2016
Interview
There was an online Aptitude round of 2 hrs with 4 sections Verbal aptitude technical Quants each were having subsections with their time limits that is each section had time limit, Questions were medium level and paper was lengthy ,then there was a coding round :
1.postfix to infix
2. lengthy question quite hard to remember.
even after compiling one of two students were shortlisted for interview
there were 3 technical interviews after which there was GD cum HR
technical interviews were easy mostly concentrated over DBMS and JAVA , little bit of DS and some standard puzzles.
Hr was very simple normal standard questions.
Interview questions [1]
Question 1
DBMS:
inner join ,Outer join ,any complex query then they asked me to explain it
JAVA :
Multithreading questions
Puzzles:
camel ,bookworm puzzle
how will you store a phonebook
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.
Interview questions [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.
Interview questions [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
