## Preparation Tips & Key Takeaways ### What I Learned - Explaining my thought process step by step is important, even if the interviewers don't provide much feedback. - Be prepared for follow-up questions on coding problems, including variations of common Lee...
The coding questions I encountered were: 1. Find the first non-repeating character in a given string. 2. Given an array, divide it into the minimum number of groups such that for each group, the absolute difference between any two elements is no more than `max...
The coding question I received was to print every odd number in a given integer list, with the following follow-up questions: 1. What if the list contains negative numbers? 2. What if some integers are so large that they do not fit in 32 bits? **My approach:**...
## Preparation Tips & Key Takeaways ### What I Learned - It's important to prepare behavioral stories aligned with the leadership principles and guide the interviewer to ask about my strengths. - Clarifying the problem constraints upfront is crucial, especiall...
The online assessment questions were: 1. Determine optimal samples: Replace all '?' characters to minimize the sum of overhead at all positions. This is a greedy algorithm problem. 2. Get maximum median: My initial approach used binary search, but only passed...
I applied in mid-March and got a quick response. The Online Assessment had two simple questions. Within a week, I received an interview invitation from an AWS team. HR mentioned that all intern interviews needed to be completed within the week. My virtual onsi...
## Preparation Tips & Key Takeaways ### What I Learned - Pay attention to edge cases in basic algorithm implementations like `memcpy`. - Be prepared to discuss optimization strategies for heterogeneous architectures. - System design questions can be very broad...
I had an onsite interview for an SDE II position. I was told internal transfers are usually a simple conversation or short interview, but it felt like a full onsite. **Round 1 (L5):** * System Design: I was asked to design a game I like. I chose Minesweeper. *...
The first coding question was: ``` The developers at Amazon are working on optimizing the capacity of their cloud system. In the system, there are n servers where the memory capacity of the i-th server is represented by the array memory[i]. A system always con...
