Initially, HR set up a round with employees who had around 12 years of experience at Goldman. The interviewer gave me a brief about the team for which they were assessing me and asked about my current role and a problem I was dealing with.

First interview round started with two coding questions. The first one was easy, and I was asked to implement it. I implemented it, and the interviewer asked me to run and test a few cases, which was pretty easy for me. The second question related to intervals, which I was able to solve within the allotted time.

After clearing this, HR asked me for four consecutive interviews. Upon requesting, it was broken into two sessions, with two rounds each. These rounds typically had a two-member panel.

First round started, and one of the interviewers asked about a rate limiter design problem, which I tackled and was building a solution for. The second interviewer asked about a programming problem, which I solved, but the interviewer found it hard to understand. He even tried to run a few cases he could think of. Everything was fine, but he didn't seem to understand the solution; he was a bit confused.

In the second session, interviewers asked about a trie-related question, and another was a recursive problem on a tree to find a pattern. I was asked to implement them, and I was able to solve both of these problems. This round was good, and the interviewers seemed fine too.

The next day, HR canceled my second session, which comprised two more interviews the following day. She told me she would come back with feedback. I emailed her after a week, and there was no response for more than 10 days after that.

Everything was fine, but I'm a bit disappointed with the HR person. They do not respond.

1. Given different intervals, provide the combined longest interval. Example: [1,2], [2,4], [5, 6] => [1,4]

2. Given numbers ["12", "9", "98"]. Combine them to form the largest number. Example: [99812]

3. Design a rate limiter.

4. Given a sorted string. Find the first 10 strings with a given prefix.

5. Recursion related topics.
