Oracle Interview Experience (On-Campus for OFSS)
Oracle visited our campus for recruiting an Associate Application Developer, for Oracle’s part of OFSS.
There were 4 rounds for the whole process
Round 1 (Online test)(2Hour) :
There were CGPA criteria 7 and above, and CSE, ESE, and EE branches (B.tech+M.tech) were allowed.

– Coding outputs (mainly on Complexity, Stack, Queue, trees, AVL trees)
– English (Grammar, Reading Compression)
– Computer Science subjects (DBMS, OS, Software Engineering)
The test lasted for 2 hours. The key here is managing time. Questions were of average level but time was not sufficient, so anyhow I first took a quick view on all questions and manage time according to them. Each section has a separate time.
A total of around 140-150 students appeared in the Online round.
Out of them, 23 students were shortlisted for the next round.
I was shortlisted for 2nd round.
