Lowe's interview questions and answers

JavaScript

  1. 1.setTimeout(fn, 0) and Promise.then - which runs first and why?

    What they're checking
    Understanding the event loop.
    How to answer
    Promise.then first - it goes into the microtask queue, which empties right after each task. setTimeout goes into the macrotask queue, later.

  2. 2.In JavaScript, why does '5' == 5 return true but '5' === 5 return false?

    What they're checking
    JS basics.
    How to answer
    == converts the type before comparing; === also requires the same type. Always use ===.

  3. 3.Write a debounce function - so a search box doesn't call the API on every key.

    What they're checking
    Practical JS.
    How to answer
    A function that keeps a timer; on each call, clearTimeout the old timer and set a new one. Only the last call runs after the delay.

Coding

  1. 4.Rotate an array right by K steps without an extra array.

    What they're checking
    Easy DSA.
    How to answer
    K = K % n. Reverse the whole array, then the first K, then the rest. O(n), O(1) space.

  2. 5.Reverse only the positions of the vowels in a string.

    What they're checking
    Two pointers.
    How to answer
    Walk from both ends; if both are vowels swap them, otherwise move the one that isn't. Include capital vowels.

  3. 6.From a room's length and breadth, how many paint cans are needed (one can covers 10 sq m)?

    What they're checking
    A home-improvement problem.
    How to answer
    Wall area = 2 x (l + b) x h, minus doors/windows, times the number of coats, divided by 10 and rounded up (ceil). Error on bad input.

  4. 7.SQL: find customers who haven't ordered in the last 90 days.

    What they're checking
    Joins.
    How to answer
    customers LEFT JOIN orders (the last 90 days) ON id, WHERE orders.id IS NULL. Or NOT EXISTS.

Design and API flow

  1. 8.A user taps 'buy online, pick up in store' - what all happens in the backend?

    What they're checking
    API flow has been reported.
    How to answer
    Order API from the cart -> check and reserve the store's stock -> payment -> confirm the order -> a pick list to the store -> notify the customer when ready. Say what happens if each step fails.

  2. 9.Design product catalogue search with filters.

    What they're checking
    System design.
    How to answer
    Products in a search index (like Elasticsearch), filters (brand, price, rating) through facets, cached results, and stock/price fresh from a separate service.

  3. 10.Why did you choose React/Node (or your stack) for your project, and what was the alternative?

    What they're checking
    Explaining tech decisions.
    How to answer
    What was needed, which options you looked at, why you chose this one, and what you would do differently now.

HR

  1. 11.What do you think about hybrid or office-based work?

    What they're checking
    Matching expectations.
    How to answer
    Give your preference honestly, but flexibly - show you understand the team's needs.

    What they're checking
