First Round, Three Coding Questions with a Friendly DQA

The interviewer is a DQA who already works there. The conversation was relaxed overall, the interviewer was easygoing and happy to talk and give hints, and the whole thing felt more like chatting while solving problems. Climbing stairs: each step you can choose from xx ways of moving, and you need to count how many ways there are to reach step n. This maps to LeetCode 70, and DP is enough. There…

A Screen Full of Probability Puzzles and Finance Basics

Let X and Y be independent Uniform(0,1) random variables. What is the probability that the product is greater than one-half? Imagine we have a deck with 52 cards and play a game: I draw one card randomly, then you draw one from the remaining 51 cards. The higher card wins. If the two cards have the same rank, we return them, shuffle, and repeat the draw until a winner is determined. Who has the h…

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

I am an older programmer. After graduating in 2016, I spent my early career doing C++ backend development at internet companies. After the pandemic, I moved into quantitative development. 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. From March through May, I interviewed intensively with…

Two Onsite Rounds, Rejected After a Two-Week Wait

The first round was an OA — I already posted about that separately, so check it out if you get the chance. After the OA I did two rounds of VO. Three rounds in total. Round 1: This interview was with a junior software engineer. He asked a few simple resume questions first — nothing to worry about, the interviewer just wants to understand your background. After that he asked some technical questio…

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.
