I applied through a recruiter and attended interviews at Prestige Technology Park in Marathahalli, Varthur Hobli. The full 5-round interview process took one day.

Actually, the first round was a written test on core Java concepts, mainly focusing on multithreading, collections, and Hibernate sessions. The second round involved two people asking for explanations of the programs I wrote in the written test, along with some technical questions.

After that, we continued to the 3rd, 4th, and 5th rounds, which were telephonic, held in their office.

Following the interviews, the manager told me to wait as he would call back soon. I waited, and after some time, I received a call. He asked me about my CTC and expected salary (he didn't ask if it was negotiable?). He then said our HR would call me next week.

However, I didn't get any call from Oracle after that. I felt really bad, wondering why he told me to wait for an HR call. After clearing those hectic 5 rounds of interviews, it was all for no use.

My advice to guys is: even if you clear all rounds, it's just luck at Oracle. Don't hope for Oracle until you get an offer letter.

Write a Java program to find the first array element that is not present in the second array.
