I applied through other source. The process took 4 weeks. I interviewed at Oracle (Saint Petersburg, Sankt-Peterburg)
Interview
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.
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.
