The interviewer was friendly. After brief introductions, I was asked to design a pagination API. I could call an external API that returns data for a specific page (e.g., input 3 to get the third page). The new API should allow users to input a number (e.g., 3...
I had one hour to complete three questions: two SQL questions and one Python question. The Python question was to invert a list of characters, keeping spaces in their original positions. For example, `['x', ' ', ' ', 'y']` should be inverted to `['y', ' ', ' '...
I had four rounds during my onsite interview. - **Round 1:** I was asked to implement transaction record pagination. The problem was straightforward. - **Round 2:** I was asked a commonly asked question which is simialr to Leetcode 981. I pretended to see the...
The interviewer structured the interview with 15 minutes for Q&A, then 15 minutes on product sense and 15 minutes on strategy. **Product Question:** Why do users care about this product? What about in 15 years? **Strategy Question:** If I were a VP, how would...
After a brief self-introduction, I was given the following coding problem: ``` # The problem we'd like you to work on is a "valid" 1-d convolution function. # That is, only perform the convolution on complete input regions. # Example: # input = 11, 2, 3, 4, 51...
## Preparation Tips & Key Takeaways ### What I Learned - Focus on practicing frequently asked interview questions. - Ensure a solid understanding of fundamental data structures and algorithms. ### Recommended Preparation #### Coding Practice - Practice a wide...
The phone screen involved a combined problem based on LeetCode 146 and LeetCode 981. Initially, the interviewer presented a variation of LeetCode 981, adding a `getAverage` method and asking me to optimize its time complexity. Then, the problem evolved to inco...
The interviewer asked how I would optimize the array-based solution. I suggested using a trie data structure. The interviewer mentioned that while it works, it might be too complex, and many candidates struggle to complete it during the interview. They asked i...
## Preparation Tips & Key Takeaways ### What I Learned - I need to be prepared for multiple coding rounds during the onsite interview. - It's important to be familiar with commonly asked system design questions like rate limiter. - Be ready to discuss projects...
