Interview Questions

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

Tabrez Z. - "First of all, I could tell that Google maps are used by billions of people around the world. Not only immensely used by the billions of people, but also they are dependent on google maps. I believe that google maps are the only map service in the world, which is providing the best services. We are collecting huge data from this service, which is very useful to predict or analyze market sentiments. We have invested a humongous amount of time, effort, and money to establish these renowned google M"See full answer

Sue G. - "Race Condition i,e multiple threads modifying simultaneously can lead to data inconsistency Operations like putIfAbsent() or computeIfAbsent() are not atomoic i.e duplicate entries or missing updates when multiple threads perform operations Data Corruption : during resizing of a hashmap by a thread, if another thread is accessing the same data , buckets can get corrupted, leading to a loss of data"See full answer

Samya S. - "Asked clarifying questions Thought through the motivation (came up with a mission and business model, modeled it on Safeway with agreement from the interviewer User segmentation both by age groups and behavior, then prioritized user group Went through user journey (both physical store and online) to identify pain points Prioritized pain points Came up with 5 solutions Interviewer picked one for me to deep dive. I went into detail on that one. "See full answer

Siddhant S. - "Question: How would you improve airport layover? Clarifying Questions What’s my role? Product Manager at a specific company? - Product Manager at the company that builds the airport Digital Product or Physical Product? - Make my own assumption Specific Airport? Country? Airline? - Airport in the US Has both international and domestic Why? Airport layovers are becoming more common as international travel picks up post COVID Increasing # of travellers Layovers as a"See full answer

Sudhansu T. - "In Ideation phase, the below points should be concentrated on. Ideation Market research Competitor Analysis in the next phase it should be conceptualisation where we define the problem, find user persona and some of the feature priortization. Next phase has to be validation where we build the MVP, do user testing, Iterate. Then comes the prototyping, Development, QA, Marketing and Position. After which we launch the product. may be a soft launch first and the proceed to full launch"See full answer

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

Shivam P. - " First, sort the array in ascending order. This ensures that we can easily check the triangle inequality condition. Use a loop to iterate through the array. For each triplet of consecutive elements, check if they satisfy the triangle inequality condition a+b>ca+b>c. As soon as you find a valid tuple, return it. If no valid tuple is found, return null. This approach is efficient with a time complexity of O(nlog⁡n)O(nlogn) due to the sorting step, followed by a linear scan of the array"See full answer

Exponent - "This is a Measure Success question with a slight twist. The twist here is we need to consider a hypothetical improvement. This changes our formula slightly - specifically we may not be able to apply a UX flow to drive analysis since we're unsure of the implementation. Instead, we'll look at core behaviors that are indicative of success. Here's the modified formula: Ask clarifying questions State the goal of the feature **Apply a UX flow to drive analysis of what to measure"See full answer
