Hi All,

I wanted to share with you my interview journey till now starting almost from april 2024. I was previously in data engineering roles and never studied DSA and system design seriously. I was quite naive during my starting time and thought how hard can it be to just get a offer at any product company/ startup (I am currently at a good PBC, 6 YOE) which was very quickly shattered. I appeared for my first interview after almost 2.5 years in april 2024.

  1. Reltio: They asked questions on java mostly, multithreading, write an example to showcase deadlock, write a multithreaded program to print odd and even numbers by 2 different threads in order etc. [Rejected]

I blew this up and realized I couldn't even create a thread and lacked on java basics and hands on code.

  1. Zepto: 1st DSA round: https://leetcode.com/problems/find-the-duplicate-number/description/ Couldn't find any clue. [Rejected]

Badly blew up, Realized at this point i really need to do DSA more seriously.

  1. Groww: Senior Data engineer role, First round was with hiring manager and I thought i went well, but recieved rejection. A question that was asked was - you have to sort 1 - N numbers using distributed computing. I talked in terms of map reduce, but ideally we can do it through external merge sort. [Rejected]

  2. Microsoft: OA round - 1 question, 30 mins, only C# language, codility platform - https://leetcode.com/problems/decode-ways/description/ I solved it before time but still got rejected, not sure if its due to plagarism. [Rejected]

  3. Amazon: SDE 2 role - OA round - 2 questions which mostly went over my head, found some online solution but times up while coding it up. [Rejected]

  4. Flipkart: SDE 3 role - 1st Machine coding round - make a cult fit type gym slot booking app. Gave working code but was grilled due to tightly coupled code, missing several points, irrelevant use of design patterns. [Rejected]

  5. Kotak: Finally a interview I was able to clear. It was a SDE 2 role, 3 rounds - 1 bar raiser (https://leetcode.com/problems/container-with-most-water/ , Tic Tac Toe low level design with DB schema, some distributed sytems questions)
    2nd round DSA: https://stackoverflow.com/questions/24495164/implementing-shuffle-functioning-in-a-music-player and https://www.geeksforgeeks.org/print-all-combinations-of-given-length/
    3rd round system design:
    Design survey monkey and analytics as a Saas, APIs, DB design, LLD and HLD flow
    [Accepted]

  6. Agoda: 1st round DSA on hackerrank - qs 1: story based little bit similar to https://leetcode.com/problems/car-fleet/ can't find the exact problem but it was of greedy type. qs 2: story based question similar to https://www.geeksforgeeks.org/longest-path-undirected-tree/
    [Rejected]

PS: This is my first time writing a leetcode post, kindly upvote if you find it useful :)
