Overall, the experience was good. However, HR did not respond or provide status updates, which was quite frustrating and required persistent follow-ups.

There were a total of five coding rounds:

1. An online coding round with pair programming. This involved writing a couple of functions and executing all test cases on the HackerRank platform.

This was followed by an interview loop that included four additional coding rounds. Each of these rounds followed a similar pattern without variation, using the same HackerRank platform to solve string manipulation-related questions.

Overall, I felt the interviews went well, but I did not receive any response. Today, I checked the Oracle career portal and saw the status was "no longer under consideration" because the job I was looking at is no longer available (I'm not sure what this means).

They did ask design pattern-related questions, such as sliding window and rate limiter concepts.

The overall experience was acceptable, excluding the HR interaction due to numerous flip-flops during interview scheduling and a lack of clarity that all rounds, including the hiring manager's, would be coding rounds.

Here are some interview topics:

• Simple string manipulation question on anagrams and counting occurrences.
• Shopping cart example.
• Blocking vs. non-blocking operations.
• REST API design.
