I applied through a recruiter. The process took 3 weeks. I interviewed at Goldman Sachs in Feb 2015
Interview
A recruiter contacted me through my LinkedIn profile. There was an initial screen with just HR questions about your resume, what type of job you would be most comfortable with, rate your programming languages in order of comfort level etc.
I then had 3 phone interviews each with a different member of the Starts team. The interviews were tailored based on each interviewer. My first interviewer had done a masters in Industrial Engineering so all questions were statistical analysis and a few brainteasers. My second interviewer was a CS major so it was all programming and algorithms. My last interviewer was a Computational Finance guy, so got asked equity and machine learning questions.
Most importantly, know your computational complexities! They will ask you to derive them, if necessary.
Interview questions [4]
Question 1
What is the computational complexity of quicksort? Derive it mathematically.
I applied through an employee referral. I interviewed at Goldman Sachs in Dec 2025
Interview
One round of coding interview (leetcode medium). Superday is 5 back to back interviews. Superday covers financial engineering (green book question, interest rate models, options, and projects on resume), coding (one easy one medium), the hiring manager interview (resume and fit)
Interview questions [1]
Question 1
Why do you want to leave your current job; what exactly do you do at your current job.
I interviewed at Goldman Sachs (São Paulo, São Paulo)
Interview
Puzzles (brain teasers), maths questions and programming challenges. The interviewers tried to understand how deep my knowledge was on each of the topics we talked about. There is no room for making stuff up, please don't try that.
Interview questions [1]
Question 1
Tell me about this X thing I see on your resume (and then they proceed to ask about every detail, in order to understand how much you actually understand)
The interview process is not necessarily specific to the role but focus mostly on technical questions. It starts with a coding test (Coderpad) followed by a series of pair interviews with strategists/technologists. Expect brain teasers, math problems (probability) and the foundation of software engineering (algorithms, data structures, etc.)
Interview questions [1]
Question 1
You have a bag with 100 identical golf balls in it. Each ball is labeled by a number between 1 and 100 (no duplicates). By paying $1 per draw, you can pick one ball from the bag. Then you can either stop and you will be paid an amount in $ equivalent to the number on the ball or you can reinsert the ball in the bag and extract again. What is the optimal strategy to maximize the gain?
