Raja raghudeep E. - "There can be multiple effects on adjusting the context window of LLM, some I can think of are below: If window size is large then more tokens are in context which could increase memory and compute costs because of O(n2) attention complexity. Larger window can help in better responses in multi turn conversations but attention dilution can also happen."See full answer

GalacticInterviewer - "Approach 1: Use sorting and return the kth largest element from the sorted list. Time complexity: O(nlogn) Approach 2: Use max heap and then select the kth largest element. time complexity: O(n+logn) Approach 3: Quickselect. Time complexity O(n) I explained my interviewer the 3 approaches. He told me to solve in a naive manner. Used Approach 1 had some time left so coded approach 3 also The average time complexity of Quickselect is O(n), making it very efficient for its purpose. However, in"See full answer

RestlessMonk - "I prefer to build a team of complementary skills than being skewed on one aspect. And generally avoid an all rockstar team. Technically, this means we will have atleast one rockstar for one skill and it is acceptable if that rockstar is just an avg performer on other skills Which person gets indexed more on which skill is a time to time exercise depending on needs of the org, product charter and career aspirations of the person."See full answer

Exponent - "This is a Design a Product question. For this, we'll want to follow the formula for success: Ask clarifying questions Identify user types, behaviors, and pain points State the goal and use cases List current solutions Improvements / net new solutions Evaluate and select solutions Measure Success Summarize Ask clarifying questions It's important to get clarity on anything unclear. This may seem like a straightforward question, but us"See full answer

Exponent - "This is posed as a tricky question at first, but we can actually approach this very similarly to a Favorite Product question. It's always good to start with identifying what type of problem you're tackling. The problem we need to tackle is essentially a variation on a Favorite Product Question: Choose a product and briefly explain what it is Who are the users? What are their pain points? How did competitors solve it in the past? **How does this product addr"See full answer

Rishabh S. - "Clarifying Questions: How do you define 45% drop in ride orders? Does it include completed as well as cancelled rides? Is it a sudden drop or a gradual decline? For all types of services/rides or anything specific? At any particular time of the day/week/month, have we observed this drop? Is it happening across all locations or in a particular region? For a particular platform? iOS/Android Most likely reasons (that we can cross-off asap): Unrest in a particular geograph"See full answer

Exponent - "This is a Technical question. It tests your ability to understand high level technical concepts. Even though your job won't have any coding involved, you'll still need to understand these concepts. Being able to cover all these topics with clarity communicates confidence in your interviewer. Unfortunately, there's no formula for technical questions, but some general tips are: Use analogies when you can Break your solution into clear, bite-size steps Don't be afraid to use examples to b"See full answer

Exponent - "You should be able to identify this as a Measure Success question. These kinds of questions are used to test your analytical skills, as well as your ability to track project progress post-launch. Recall the strategy for tackling them methodically and thoroughly: Ask clarifying questions State the goal of the feature / product Behavior Mapping / UX Flow Mapping Provide criteria to prioritize metrics Prioritize metrics Summarize Let's begin!

Lakshman B. - "As we can pass info to only one child at a time, I told that from any given node, we have to pass the info to that child(of this node) which has the largest subtree rooted at it. To calculate the subtree sizes, I used DFS. And then to calculate the minimum time to pass info to all the nodes, I used BFS picking the largest subtree child first at every node. I couldn't write the complete code in the given time and also made a mistake in telling the overall time complexity of my approach. I think t"See full answer
