Technical Interview Questions

Tony C. - "That I had not been a PM for a formal ML product. But good models need sound data and my five years of sql writing and ensuring that DWHs and marts had the data they needed for reporting would be very relevant"See full answer

Satyam S. - "Binary search is commonly used for searching elements in a sorted array. Most searching algorithms take O(n) time, but binary search operates in O(log(n)) time complexity. function binarySearch(arr, target) { let first = 0; let last = arr.length - 1; // Adjusted to correctly represent the last index while (first target) { last = mid - 1; } "See full answer

Saurabh S. - "Basic Approach As BST inorder traversal will result in a sequence of increasing order. Store that order in a vector and get the k-1 index to get the Kth smallest element, similarly access the N-K+1 th element will be the Kth largest element Time Complexity: O(n) Space Complexity O(n) Space Optimized Approach For Kth smallest , start inorder traversal, and keep a counter, decrement the counter when you access the node element. When the counter turns 0 that elementwill be the Kth smal"See full answer

Deepak M. - "Imagine there's a new toy you've always wanted, but it's not quite perfect. Maybe it's missing a feature you'd love, or it's a bit too complex to use. That's where a product manager, or PM, comes in! Think of a PM like the captain of a shipbuilding this amazing toy. They work with different teams, like the designers who make it look cool, the engineers who build it, and the marketers who tell everyone about it. They listen to people like you, who use the toy, to understand what they like and wha"See full answer

Ali H. - "CIDR (Classless Inter-Domain Routing) -- also known as supernetting -- is a method of assigning Internet Protocol (IP) addresses that improves the efficiency of address distribution and replaces the previous system based on Class A, Class B and Class C networks."See full answer

Ashenafi B. - "I was able to come up a solution but I ran out of time."See full answer

Erjan G. - "i did not know ,but the answer is parquet is column-oriented, avro is row-oriented"See full answer

Anonymous Flamingo - "In Python, an "oops" (Object-Oriented Programming) concept refers to a programming paradigm that is based on the idea of objects and classes. OOP allows developers to model real-world concepts and create reusable code blocks through the use of inheritance, polymorphism, and encapsulation. Here are some common OOP concepts in Python: Class: A class is a blueprint for creating objects. It defines the attributes and behaviors that objects of that class will have. Object: An object is an insta"See full answer
