Interview Questions

Exponent - "This is another Fermi problem — an estimation or approximation problem with limited information and back-of-the-envelope calculations. There's no right answer: interviewers want to understand how you think and how well you can explain your reasoning, rather than what you already know. Recall the formula for Fermi problems: Ask clarifying questions Catalog what you know Make equation(s) Think about edge cases to add to equation **Breakdown components of your"See full answer

Madeline S. - "I like Spotify, because Spotify has a social element and an element of community that other music apps do not. The ability to see what friends are listening to, make playlists/jams with friends, and enjoy the "wrapped" at the end of the year (which is also an incredible social sharing tactic), is what sets it apart from other apps."See full answer

Anonymous Mollusk - "My weakness was stage fright and talking in front of a large audience. This TPM role does offer me an opportunity to do both but not at the scale at which impacts my day to day role. Also over many years I have taken remedial action e.g. joined a Toast Masters club to overcome my weakness."See full answer

Gabriele G. - "Using a DFS approach, computing all the distances from typing import List from collections import deque def shortestCellPath(grid: List[List[int]], sr: int, sc: int, tr: int, tc: int) -> int: if sr == tr and sc == tc: return 0 nRows = len(grid) nCols = len(grid[0]) distances = [] stack = deque([(sr, sc, 0)]) visitedSet = set() while stack: nodeR, nodeC, nodeDist = stack.pop() if gridnodeR == 0 or (nodeR, nodeC) in visited"See full answer

Exponent - "This is a Diagnosis Question. The goal of Diagnosis questions is to test whether the interviewee is organized and logical in their product approach. It also tests whether the PM is exhaustive in causes for decreases and whether they provides realistic solutions to the problem. Let's follow the Diagnosis Question formula: Ask clarifying questions Propose high level reasons for a drop Gather context (TROPIC) Establish a theory of probable cause Test theories "See full answer

Konstantin P. - "Count how many 1 and 2. calculate how many remaining items with '0'. Override existing data with knowledge of how many '0','1','2' in that order; TC=O(n), SC=O(1)"See full answer

RockyBalboa - "Clarifications: Do we consider window for any building or only residences? I will ignore windows in cars for complexity reasons. Pardon my ignorance for not knowing the size and population of Tehran, Would you mind sharing some inputs or is it okay if pick some Randoms? Analysis: Tehran is ~300 sq. miles in terms of land area with an overall population of 9 MM with an average 3.5 members per household. _I will be moving with windows for residences only and then gut check my response"See full answer

An D. - "First find the node that we need to delete. After it's found, think about ways to keep the tree BST after deleting the node. a. If there's no left or right subtree, we found the leaf. Delete this node without any further traversing. b. If it's not a leaf node, what node we can use from the subtree that can replace the delete node and still maintain the BST property? We can either replace the delete node with the minimum from the right subtree (if right exists) or we can replace the delete"See full answer

Surbhi G. - "I would start by understanding the project requirements and creating a detailed plan with clear milestones. I’d allocate resources effectively and use project management tools to track progress. Following an iterative development approach, I’d ensure regular testing and reviews. Finally, I’d deploy the solution, provide support, and gather feedback to make any necessary improvements." 4o mini"See full answer

Abhishek s. D. - "I would get an personal understanding of the pain-points my customers, & business teams are facing. In my experience, spending more time, going deeper in the problem discovery helped me get a rough idea of the how important this problem is. If this is not resolved - what could be the consequences for our users & the business. Given this broad idea, I just simply evaluate them on value vs effort scale. The higher the score, higher the priority. Effort could be in T-shirt size or sto"See full answer
