Oracle Developer interview questions

The question was a mix of OS, OOPS, DSA, and CN. They also asked about my internship experience. The OS questions were fundamental, like deadlock and explaining why it occurred. The DSA question I got was about Implementing a stack using two queues. And queue using two stacks. After that, a few more basic string questions. Now, coming to CN, one team went into depth about it, while the other didn't even ask for it.
