Oracle

The first round was telephonic. Once I cleared that, they called for a face-to-face technical discussion. It was for a senior Java role. I was told it was for core Java with deep knowledge on algorithms and data structures.

I had three levels of interview: * Technical * Manager level * Director level I spent at least one hour in dedicated discussion at each level. The first round was purely technical and did not even include the usual "Introduce yourself" question. T

There were a lot of rounds. I cleared till the 4th round, and still, a few more were left. Most of the rounds, they asked the same questions: singleton, threads, and the collection framework.
