Auto-Rejected Before the OA Deadline Even Hit

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 2s

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 Quantitative Analyst math test and options theory interviews

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 round

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 Problem

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 strategy

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 Quantitative Analyst interview: options intuition, probability, and a superday

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 rejection

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 Software Engineer interview with a one-hour coding assessment

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 Quantitative Analyst interview with timed probability and option-pricing questions

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…

A 3-Problem Codility OA With a 5-Part Robot Pathfinding Puzzle

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 <= 200,000. Then several rounds of a tournament are held. In each round, players are paired off left to right (#1 v…

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.
