This time I will share a complete Amazon SDE VO is a two-round interview, the overall rhythm is very standard, a typical LP combination of deep digging + high-frequency algorithm questions. Each round is 2 BQ + 1 coding, and the time is very accurate: half an hour for BQ, half an hour for coding, and every question will be asked downwards. Depth is more important than breadth.
Timeline
- Apply in early November
- 12.14 OA received
- Complete OA on the same day
- 26.1.8 Make an appointment with VO (there will be an HR call during the period to confirm basic information)
- 26.2.8 Two rounds of VO loop
- The preparation time is about 1 month
The timeline is not too short, and the time to actually prepare for VO is actually very precious, especially the arrangement of LP materials.
Amazon SDE VO Round 1
The interviewer was a Korean girl who spoke very softly and politely. After introducing herself, she briefly talked about her resume, and then asked about some BQ+coding related to the project. The whole process was very enjoyable.
BQ:
1. Proudest project A project that exceeded expectations.
2. Tight deadlines How do you prioritize when time is limited?
Coding：
Given an array, the number in each position represents the maximum number of steps that can be jumped forward from here. Ask if it can jump to the last position.
Problem-solving ideas: Use greedy to traverse the array and maintain the farthest subscript that can currently be jumped to in real time. If it is found when traversing a certain position that it exceeds the farthest distance that can be reached, it means that it is stuck; otherwise, it continues to update the farthest distance. Finally, just check whether the farthest distance is greater than or equal to the end of the array. The complexity is O(n), there is no extra space, you can just go through it after writing it, and there is no follow up.
Amazon SDE VO Round 2
The interviewer for this round was a handsome Caucasian guy. He introduced himself + bq at the beginning. It took almost 20 minutes. The interviewer worked in the retail industry and briefly introduced the team.
BQ:
1. Tight DDL, what sacrifices have been made and what problems have been solved To satisfy Tight DDL. Follow up asked about the team's division of labor, how to understand mgr's expectations, and how to schedule progress.
2. How do you identify risks and adjust plans when you are unable to perform? Follow up the opportunity to detect the problem and communicate with the team, and what to do if you redo it.
Coding:
This time it is a high-frequency question, find the Kth largest element in the array. Using Heap, the interviewer asked whether it is better to use the maximum heap or the minimum heap, and why not use the maximum heap. It is easy to write code that repeats push/pop when doing it. Please check it after writing.
Sprint FAANG｜OA stable AC + VO full running support
If you are also sprinting for a big company, we here are already very familiar with the OA format of Google and Amazon. We have done a lot of practical reviews of high-frequency question types, platform rhythm, and time allocation. Conventional coding questions can basically stabilize the AC within 30 minutes. OA / from major companies such as TikTok and Meta VO assist We also follow up on a long-term basis, from OA to VO, accompanying you all the way.
