Software Engineer Interview Questions

Chitapuram N. - "Since there is a need for the data to be accurate and consistent without any latency to allocate a spot, can't the data be synchronously synced to replicas after every write as the number of writes are not many per min, instead of read lock phenomena Let me know if i am on a wrong thought here."See full answer

dreamingincode - "In the API design, the interviewer is switching between RPC style (operation based endpoints) and REST style (resource oriented). Sticking to one convention and explaining why it is preferred over the other e.g. REST if the twitter domain maps nicely to resources e.g. /tweet or /follower or /user would help to create a more consistent and unified API. It would make it easier for clients to integrate with the API as well."See full answer

Nagendra S. - "Assumptions: Platform: iOS/Android and Web Application Service Type: Renting Bicycles (hourly, daily, weekly), possibility of buying or selling Geography: Focusing on Asian markets, e.g., India, where bicycles are a popular mode of transportation Role: Product Manager at Microsoft Objective: Design an app focusing on customer engagement and new customer acquisition Setting the Stage: Why a Renting Business? Market Potential: In Asian markets, a si"See full answer

Jatin S. - "public int minInsertions(String s) { int n = s.length(); int dp = new intn; for (int len = 2; len <= n; n++) { for (int i = 0; i + len - 1 < n: i++) { int j = i + len - 1; if (s.charAt(i) == s.charAt(j)) { dpi = dpi + 1; } else { dpi = 1 + Math.min(dpi + 1, dpi); } } } return dp0; } `"See full answer

Kapil P. - "Sounds like both the features requests address different problems, although it should be clarified in my opinion. I'd try to dig deep into why the customers are raising the requests to uncover the pain points. Questions like the following would help: "How are you currently solving it?" "What does it mean for you in terms of Cost or productivity?" (based on the context of the product) "Have you searched for an alternative?" Descriptive answers for the above questions should tell us if the"See full answer

Ra R. - "In my time at Snapp! I was in charge of communicating the product backlog to our CEO. We had a shared Jira board that he had access to and I made specifically for him. One day he saw me in the office and said he doesn’t know anything about our backlog and that’s because I failed to communicate with him. I got upset at first because of the fact that I made the dashboard exclusively for him. But I tried to ask questions to understand his point of view in depth. He then mentioned he doesn't have t"See full answer

Ashish D. - "This is a geometric variation of the "Sliding Window" technique. The core challenge is converting a 2D coordinate problem into a 1D linear problem using angles. The standard approach is the Angular Sweep. By converting the Cartesian coordinates (x,y) of every tree into Polar coordinates (specifically the angle θ), we can process the trees based on the direction they lie in relative to the observer. The Strategy Coordinate Translation: Calculate the relative coordinates (Δx,Δy) for"See full answer

Syed I. - "I use a data driven approach by ensuring there is a deep-dive on all alternatives. My approach to tradeoffs is around how to achieve the customer experience needed. I ensure there is an immediate path to green for a solution and a follow-up solution addressing the problem rightly."See full answer

Rjj - "I tried solving this problem and here is the recorded video for the answer. https://www.youtube.com/watch?v=d1tOkeQjyI4 And here is the link to Excalidraw board - https://excalidraw.com/#json=uabNFHcZm5qNh8CInMvyh,Wn9Vf1ZhGdl_iBCQYFkYdw"See full answer

Kishor J. - "we can use two pointer + set like maintain i,j and also insert jth character to set like while set size is equal to our window j-i+1 then maximize our answer and increase jth pointer till last index"See full answer

Simon O. - "Functional Requirement Ingest Book Reviews in real time User in the website needs specify title tho search books, return response is the list of reviews on the books. Non Functional Requirement: User get real-time book reviews> It nees to handle the search among 1 million of active users daily"See full answer

Pushkar G. - "Assumptions - Multiple reader/writer threads issue set() [with transaction] and get() operations concurrently All data can fit into memory. Requirements - Good performance (ex. less lock contention) Optimize memory footprint (ex. don't store stale entries in memory) Naive Approach - Wrap a standard hashmap/dictionary with reader-writer lock. We can also shard the map to reduce lock contention (ex. 32 segments for 32 core cpu) Allocate local buffer to a writer when a transacti"See full answer

Zakery K. - "Conflict is a GREAT opportunity to really demonstrate that you care about someone and, through effective conflict resolution, build stronger authentic relationships with the people you work with. When faced with conflict, I prioritize understanding all perspectives involved. I start by actively listening to the other parties: asking clarifying questions to pinpoint the source of the conflict, reflecting back what I'm hearing to make sure I understand them correctly, and ultimately identify"See full answer

Anni P. - "I firstly discuss the brute force approach in O(n^2) time complexity , than i moved to O(nlogn) tine complexity than i discussed the O(n) time complexity and O(n) space complexity . But interviewer want more optimised solution , in O(n) time complexity without using extra space , The solution wants O(1) space complexity i have to do changes in same array without using any space . This method is something like i have to place positive values to its original position by swapping and rest negativ"See full answer
