Siemens

As part of the interview process, I was invited to the office where I first completed an online exam. After the assessment, I proceeded with a technical interview session at the office as well.

Written - Very conceptual questions from core Java. Technical - * HashMap internal implementation. * Why we need HashSet when we have HashMap. * Find duplicates in an array program. * Deep copy vs. shallow copy program. * Singleton - all categories

No defined interview process. You enter in a room with a couple of engineers, some of whom may even be from another discipline. Some of them are engineers you will not work with. Some of them are not experienced in the job you applied.
