AMAZON CHIME INTERVIEW CODE
I discussed the approach clearly and then wrote a clean code for it. Given a graph, I had to find whether the given graph is a tree or not.After this, he gave me a coding question. For the starting 30 mins, he asked about my previous works and again some behavioral questions. Interview round 4 (Bar raiser round): A senior engineering manager at Amazon took this round. I optimized it, and then he asked me to write code for it and at the end, we discussed the complexity of the algorithm. I initially gave him a brute force approach, and then he asked me to optimize it. The problem was a variation of Stock Buy and Sell to maximize profit. He was very much impressed by my previous work and then in the last 15 min, he asked me a coding problem. He asked some behavioral questions in between based on those experiences. We had a detailed discussion about my projects in the previous company. Interview round 3 (Hiring Manager round): For the starting 45 min, we discussed my work in my previous company. I answered all of them properly and then at the end the interviewer asked some behavioral questions based on my past work experiences. He then asked me about thrashing, virtual memory, caching, and real-life example of caching.
AMAZON CHIME INTERVIEW MAC
The interviewer then asked me about the DNS resolution process, the difference between MAC address and IP address, what are class A/class B/ class C IP addresses. He then asked about the complexity of the code, and we had a very good discussion on this. The interviewer asked me to write the code and he was impressed by the approach I used. I solved the problem using recursion very easily and use memoization to optimize the code.

He asked me about the complexities of both the solutions. I solved both the problems and wrote a clear code for both of them.
