  Codility OA, 115 Minutes, Three Easy ProblemsDRW · Software Engineer · Intern · Online Assessment · Oct 2026

  Overall pretty easy, with plenty of time to spare. The first two problems have no complexity requirement, pure brute force is fine, and the algorithm for the third one isn't hard either. Given an array, you can change the value of any three numbers. What is the smallest possible difference between the max and the min? Given a string made of lowercase letters, define a balanced string as one where…

  Auto-Rejected Before the OA Deadline Even HitDRW · Quantitative Researcher · New Grad · Online Assessment · Sep 2026

  Rejected

  I cold-applied online to DRW's US New Grad Quantitative Researcher role. Less than a week after applying, I got an online assessment invite. The email said the OA link would expire in seven days, and there was no other deadline notice anywhere. Then, five days later, I got an email saying I hadn't finished the OA in time, and I was flat-out rejected. But the OA link was still valid, so I went ahe…

  A Greedy Deletion Problem on a String of 1s and 2sDRW · Software Engineer · New Grad · HR Screen · Aug 2026

  I got a string greedy problem: Given a string digits made up only of '1' and '2', which represents a positive integer. You can delete 0 or more characters from it, and after the deletion: the number of remaining '1's must be even; the number of remaining '2's must also be even; and, while satisfying those first two conditions, the final integer should be as large as possible. Note that you can on…

  Drw Holdings Quantitative Analyst timed probability assessmentDrw Holdings · Quantitative Analyst · Online Assessment · Apr 2026

  I started with a timed online math and probability assessment. The questions felt genuinely hard, and the time limit was strict. My impression was that it tested how quickly I could work through probability mechanics. When I didn't make it through that stage, the process effectively ended there. In another attempt, I got further and kept running into probability and options concepts. After an ini…

  Drw Quantitative Analyst math test and options theory interviewsDrw · Quantitative Analyst · Other · Apr 2026

  After a recruiter call, the process moved into a math and probability test. It was difficult enough that it didn't feel like a formality. Then came an HR screen followed by several interviews across different teams, with questions focused heavily on probability and option intuition. Early in the process, I was told that option theory was something they taught internally and wouldn't necessarily b…

  Drw Software Engineer interview reaching the fourth technical roundDrw · Software Engineer · HR Screen · Apr 2026

  I made it as far as the fourth technical round. The process felt like a series of technical screens that built on one another. Eventually, I reached a C++-focused interview with a C++ problem. After that, the conversation shifted to my personal projects, which was a welcome change from the problem-solving questions. I had already completed an HR call earlier in the process. Overall, the structure…

  A Greedy String-Parity Coding ProblemDRW · Software Engineer · New Grad · Other · Mar 2026

  I ran into a greedy string problem. Given a string digits made up only of the characters '1' and '2', representing a positive integer, you can delete zero or more characters. After deleting, the requirements are: The remaining '1's must appear an even number of times. The remaining '2's must also appear an even number of times. Subject to those two conditions, the resulting integer should be as l…

  Drw Quantitative Analyst interview focused on competitor strategyDrw · Quantitative Analyst · Other · Mar 2026

  What started as an unusually strategic conversation quickly felt unlike a normal hiring process. My initial discussion was with the head of the business, and the focus wasn't on my background or skills. Instead, I was questioned about what the firm's competitors were doing, where they were making money, and what ideas they might be using. The tone made it seem as though the goal was to learn abou…

  Drw Holdings Quantitative Analyst: technical interview and superday with a brief brain teaserDrw Holdings · Quantitative Analyst · HR Screen · Feb 2026

  I had a relatively short, structured process that began with an HR screen, followed by one technical interview and then a superday. The interviewers were thoughtful and easy to talk to, and they seemed willing to give feedback throughout the process. The technical portion focused on quantitative thinking. It didn't feel like they were trying to trick me with obscure material. The goal seemed to b…

  Drw Quantitative Analyst interview: options intuition, probability, and a superdayDrw · Quantitative Analyst · Online Assessment · Feb 2026

  My process started with an online assessment focused mostly on probability. The math felt grounded enough to be solvable, but it was still demanding under the time limit. After that, I had a semi-technical HR conversation, followed by the technical interview phase. The technical portion combined behavioral questions with quantitative problems. I was asked about options pricing and the underlying…

  Drw Customer Success Engineer interview: Three back-to-back interviews followed by a location rejectionDrw · Customer Success Engineer · HR Screen · Jan 2026

  I started with an internal recruiter reaching out about a very senior trade support type of role. My first call was with HR, and it felt like it went well. I then spoke with the hiring manager about my background, the team, and what the role involved. The conversation felt a little unfocused on their side, but it was still decent overall. The role I initially interviewed for didn't work out becau…

  Drw Holdings Customer Success Engineer interview, role reopenedDrw Holdings · Customer Success Engineer · HR Screen · Jan 2026

  I interviewed for a Software Engineer path that grew out of a need for someone very senior in trading support. The process moved at a moderate pace and focused heavily on experience fit. I first spoke with an internal recruiter about my background and why I was interested, then moved to a hiring manager interview. That conversation focused mainly on my experience and learning about the team and r…

  Drw Holdings Software Engineer, OA-first process and technical onsiteDrw Holdings · Software Engineer · Online Assessment · Jan 2026

  Rejected

  I went through an OA-first process that ended with an intense technical onsite. The structure was clear, but I didn't receive an offer. The online coding assessment had several LeetCode-style questions. I scored highly, then didn't hear back about the next step. Another version of the process began with a proctored OA. After that, I had a technical interview with an engineer from the team I was m…

  Drw Quantitative Analyst interview with timed probability and option-pricing questionsDrw · Quantitative Analyst · HR Screen · Jan 2026

  The process felt structured from the start. I went through an HR screening and then entered a technical interview phase. The tone there was more laid-back than I expected, and the interviewers were thoughtful and willing to keep things moving. Overall, it felt standard, with a clear sequence from screening into technical evaluation and no random detours. The math and probability section involved…

  Drw Software Engineer interview with a one-hour coding assessmentDrw · Software Engineer · Online Assessment · Jan 2026

  Rejected

  The process began with an online coding assessment that took me about an hour, even though it was described as a roughly two-hour test. I felt confident after finishing it, but I didn’t hear anything afterward and received a rejection notification a couple of days later. I also interviewed with DRW for a technical role in Singapore, and that process took much longer than I expected. I completed e…

  Drw Holdings Quantitative Analyst seven-question math test and technical roundDrw Holdings · Quantitative Analyst · Other · Dec 2025

  Rejected

  I remember the process feeling intense from the start. It began with a timed math test containing seven questions. The limit was about 45 minutes, and the topics included linear algebra, probability, optimization, and brain-teaser-style problems. The questions were difficult and required quick work, so I felt that small mistakes could compound fast. After the initial stage, I had a Zoom technical…

  Drw Holdings Quantitative Analyst interview: probability, Fermi questions, and a market-making gameDrw Holdings · Quantitative Analyst · Online Assessment · Nov 2025

  Rejected

  My process started with an online assessment and then moved to a video interview. The OA felt manageable compared with some of the harsher versions I'd heard about. It covered linear algebra and probability, and the live interview extended those topics into more traditional quant reasoning. The interview included expected value and basic probability questions, a few Fermi-style problems, and some…

  Drw Holdings Software Engineer interview with a 2.5-hour Codility assessment and superdayDrw Holdings · Software Engineer · Online Assessment · Nov 2025

  Rejected

  I went through an online assessment and technical sequence that moved quickly from testing to rejection, with very little positive feedback. The Codility OA was LeetCode-style. The technical interview covered algorithms and data structures, along with operating systems, networking, and system-design topics. In one version of the process, the final stage was a superday after the first technical ro…

  Drw Holdings Software Engineer interview with a 45-minute C++ technical roundDrw Holdings · Software Engineer · Online Assessment · Nov 2025

  Rejected

  I ran into a C++-heavy interview loop where the main challenge was low-level correctness and syntax rather than just LeetCode-style problem solving. The process started with an assessment and then a short first interview. In a 45-minute C++ technical interview, I was tested on C++ knowledge and low-level details, with less emphasis on pure LeetCode. In a similar journey, I solved a LeetCode-like…

  Software Engineer interview at Drw Holdings: Python take-home and unanswered emailsDrw Holdings · Software Engineer · HR Screen · Nov 2025

  Rejected

  I ran into communication gaps and long periods of silence during the take-home and scheduling steps. That made the experience frustrating, even though I completed everything. I first had a friendly HR conversation and then received a small Python coding or homework task. I submitted it and was expected to have a front-facing technical interview, but I never heard back. In another path, I agreed t…

  A 3-Problem Codility OA With a 5-Part Robot Pathfinding PuzzleDRW · Software Engineer · Intern · Online Assessment · Oct 2025

  I applied to DRW Singapore for the SWE C++ Internship. The first round was a Codility OA, 150 minutes for 3 problems. There are n people, each with a distinct ability value in [1, n]. You're given a[i], the ability value of the i-th person. n is guaranteed to be a power of 2, with n
