Oracle GBU Interview Experience

Technical Round 1:

• The interviewer started by asking me to introduce myself and discuss my current project.
  We had a detailed conversation about the project and its specifics.

• Language preferences were explored, and I was asked whether I was more comfortable
  with C++ or Java. I conveyed my proficiency in both languages, and then I explained the
  differences between procedural and object-oriented programming as requested.

• The interview included code snippet challenges to determine their outputs. This tested my
  programming concepts and problem-solving skills.

• The concept and implementation of a singleton class were discussed next. I provided a
  clear explanation and even wrote code for a singleton pattern during our conversation.

• Multi-threading was brought up as another topic. I was asked to explain the concept and
  showcase how multi-threading works through sample code.

• The interview also involved two coding tasks. The first task required me to write a query to
  find duplicate records in a database table. The second task was about finding employees
  and their respective managers based on provided data.

• Database-related questions revolved around various types of joins and their applications in
  SQL queries.

• To assess my Java knowledge further, I was asked to differentiate between primitive and
  non-primitive data types and provide sample code snippets to determine their outputs.
  PS:Throughout the interview, the focus was more on discussing concepts rather than coding
  exercises, as the interviewer mentioned that they don't have standardized coding questions
  for me after looking my resume.
  Verdict: Failed

Technical Round 1:

• The interviewer began by asking me to introduce myself.
• We discussed my current project, and I was requested to draw the entire procedural flow
  happening in the project.
• I was asked to rate myself in data structures and algorithms, and I rated myself as an 8 out
  of 10.
• The interviewer inquired about the algorithms I knew, and I mentioned some of them.
• He specifically asked about BFS and DFS, and I confirmed that I was familiar with both.
• For DFS, I was asked to write pseudo code and explain it using a recursion tree.
• The interviewer presented a grid with alphabets and a target string, and he asked whether
  we could reach the target string by moving only right and down. I explained that we could
  solve this using DFS and I mentioned recursive and memoization methods.
• My Java knowledge was assessed, and I rated myself an 8 again. I was then asked to
  provide a real-world example of Object-Oriented Programming (OOPs).
• I was asked to explain the difference between the "while" and "for" loops.
• The interviewer presented a parenthesis matching question and asked me to solve it using
  stacks.
• I was asked about the data structures and its typed and the difference between
  implementing a stack using a linked list and an array.
• The interview concluded with the interviewer asking if I had any questions for them.
