Algorithms, Data Structures, Bash, and Dice

Short version: two algorithm questions, one data-structure question, one development-related question, and one statistics question. For an array of n positive integers arr[n] and an integer k, a subarray is good if it contains at least k distinct integers. Find the minimum length of a good subarray; otherwise return -1. Given a list containing an odd number of positive integers, you may remove ex…

A Three-Month Process Ending in Rejection

My most recent job was developing trading infrastructure in the Singapore office of a small quantitative firm, and my former employer laid me off in March.

OA With Two Coding Questions and an All-or-Nothing Pass Bar

Just finished the Squarepoint OA, sharing the two coding questions. The first question was about maximizing store revenue. Given n items, each with quantity[i] representing the remaining stock, the price equals the quantity. There are m customers, each buying one item, and the goal is to maximize revenue. I solved it with a max heap — each time popping the largest, selling it, then pushing it bac…

Six-Question OA With Rotating Questions

Squarepoint's OA has 6 questions total. The first four are probability, statistics, and reading a piece of code to analyze its time complexity. The fourth question gives a scenario and asks which kind of bias in statistics the scenario describes. None of these are hard — you can finish them in 5-10 minutes or even faster. The last two questions are coding. The first one is easy: a store has n dif…

What are interview experiences?

An interview experience is a candidate's own account of a hiring loop — not a question bank entry. It tells you the shape of the process: how many rounds there were, what each round actually tested, how long the gaps between them ran, and what the recruiter said at the end. That context is the part a question list cannot give you.

How to read them

Weight recent write-ups more heavily — interview loops change, often within a year. Read several for the same company and role rather than one: a single account tells you what one interviewer asked, while five tell you what the bar is. Note the outcome badge too, since a rejection write-up usually explains the gap far more precisely than an offer one.
