What Is the SIG Problem Solving Assessment?

The SIG Problem Solving Assessment is the first screening phase for trading and research positions at SIG, typically occurring before the first phone interview. It is administered by a third-party testing company called Mercer Mettl. The test is also known as the SIG Online Assessment, formerly the SIG Quantitative Evaluation.

This aptitude test features nine numerical questions, to be answered within 60 minutes. Like other trading companies, such as Optiver and Citadel, the SIG Online Assessment is considerably challenging.

Note: The SIG Problem solving Assessment used to be called the SIG Quantitative Evaluation. It featured 14 questions to be solved in 20 minutes. This is no longer the case.

What does the SIG Online Assessment Measure?

The tests questions are mostly about probability, especially expected value. However, there will typically be at least one deductive logical question, and one single-variable calculus question. The assessment’s name betrays its primary purpose: to evaluate the candidate's ability to understand a problem and sketch optimal routes toward the solution, using their critical thinking skills.

 Is the SIG Maths Assessment Hard?

Since mental maths are not the central focus of the exam, you will be allowed a calculator as well as draft paper and a pen. The main difficulty lies not in calculation but in approaching the question correctly and laying down operational steps to finding the answer effectively.

To this end, practice can make a significant difference. Read on to solve sample SIG problem-solving test questions, take our numerical practice tests, or read about other finance and investment banking assessments.


SIG Online Assessment Questions and Answers

Below, you will find three questions in the style of the SIG Online Assessment, in increasing difficulty. There are two expected value questions and one combinatorics question. Full solutions are provided. In addition, you will find general tips for the SIG Problem-solving Assessment.

Note: SIG Online Assessment questions are presented in multiple-choice or open-ended formats. In case of an open-ended question with a non-integer solution, you will be asked to submit your response in the most simplified fraction form.

Question 1

A deck of 18 custom playing cards is numbered from 1 to 18. A card is drawn 6 times with replacement. If X is the number of draws that result in a prime number, what is E(X)?

View Explanation

The answer is 7/3

This is a question of binominal distribution. We can think of each card draw as a trial. A successful trial is when a card with a prime number is drawn from the deck. 

First, let’s compute the probability to draw a prime numbered card in a single draw. Within [1-18] there are 7 prime numbers (2,3,5,7,11,13,17). Thus, the probability to draw a prime numbered card in a single draw is  

Since this is a binominal distribution, we can compute the expected number of card draws according to the following (n= number of draws):

Tip: This question requires you to understand the concept of binomial distribution. Other concepts of probability you should brush up on before the exam include combinatorial probability, expected values, and conditional probability. Combined, these will help you calculate the likelihood of various events.

Question 2

Three printers are independently printing pages. The first printer experiences a paper jam 25% of the time, the second printer 20% of the time, the third printer 15% of the time. What is the probability that exactly two printers will have a paper jam on the same day?

View Explanation

191/400

This question combines combinatorial thinking with probability. 

To find the probability that exactly two printers will have a paper jam, we need to consider all the possible scenarios in which two out of the three printers have a paper jam. Then, we will compute the sum of the probabilities of these scenarios. 

Printer 1:  

P(paper jam) = 0.25

P(no paper jam) = 0.75

Printer 2:  

P(paper jam) = 0.2

P(no paper jam) = 0.8

Printer 3:  

P(paper jam) = 0.15

P(no paper jam) = 0.85

Scenario 1:  

Printers 1 and 2 have paper jam, and printer 3 doesn’t.  

The probability for scenario 1 is:

0.25×0.2×0.85=0.04250.25×0.2×0.85=0.0425

Scenario 2: 

Printers 1 and 3 have paper jam, and printer 2 doesn’t.  

The probability for scenario 1 is:

0.25×0.8×0.15=0.030.25×0.8×0.15=0.03

Scenario 3: 

Printers 2 and 3 have paper jam, and printer 1 doesn’t.  

The probability for scenario 1 is:

0.75×0.2×0.15=0.02250.75×0.2×0.15=0.0225

Thus, the probability that exactly 2 printers will have a paper jam is the sum of probabilities of the 3 scenarios we listed:

Tip: Practise using a wide variety of question types. This will not only familiarise you with the different subjects covered on the exam, but also allow you to develop problem-solving abilities above-and-beyond specific topics or question types. Remember, the test is just as much about strategising and integrating knowledge as it is about maths.

Question 3

A Robot is trying to get from point A to B without overshooting. The robot is programmed to go up or right, and to always alternate its step size from moving 1 unit in a single direction to moving 2 units in a single direction. How many ways are there for the robot to arrive from point A to B?

View Explanation

256

First let’s look at the facts of the question:

To get from A to B the robot must move 10 units to the right and 4 units upwards = a total of 14 units.
The robot can only go up or right and always alternates its step between 1 and 2 units. Thus, it can either start with a 1-unit step or a 2-unit step.
Let’s see what happens when the robot starts with a 1-unit step:

1 , 2 , 1 , 2 , 1 , 2 , 1 , 2 , 1  after 9 steps the robot has passed 13 units, leaving only 1 unit to the next step. Since the next step must be a 2-unit step and the robot can’t overshoot point B, we learn that when starting with a 1-unit step isn’t possible.

Let’s see what happens when the robot starts with a 2-unit step:

2 , 1 , 2 , 1 , 2 , 1 , 2 , 1 , 2  after 9 steps the robot has passed exactly 14 units.

Between each step, from the 1st step to the 8th step, the robot has 2 options: to go up or right.

As for the 9th step – since the robot needs to get exactly to point B, for the last step the robot will have only one direction to choose – the direction of point B.

Thus, the number of possible routes for the robot is.

Tip: Logical brainteasers like the third practice question require you to break the answer down into discrete steps. Practise this style of thinking by solving more logical problems, focusing on how to turn a complex solution into a manageable sequence of steps. You will find your results on the SIG Online Assessment much improved.

The SIG Interview

Throughout your SIG recruitment process, you will typically be required to undergo three rounds of interviews: two over-the-phone and one face-to-face.

First Phone Interview

On paper, this is an HR interview to get to know you, your interpersonal skills, and your fit with the organisational culture.

In practice, the HR representatives are required to be well-versed in maths and probability, and you will face five technical questions in addition to personal questions. You can expect mainly probability questions, including expected values and Bayes’ theorem. These will be similar to questions you have already faced on the SIG Online Assessment, so there is no reason to worry.

Second Phone Interview

Your second phone interview will be with a member of the SIG development team. It will be more competency based and require you to discuss your skills and knowledge.

On-site Interview

Your final interview will be face-to-face and will aim to confirm your identity, skills, background, and expertise. By this point, you are very close to receiving an offer. Smile, be courteous, and get to know your (soon-to-be) coworkers.


3 Interview Tips

  1. Don’t Panic!
    It’s easy to get lost in your own thoughts when required to solve technical problems in front of SIG hiring managers. Don’t fret. Remember, they are not looking for a solution, but rather for a calm and settled approach to problem-solving. Think out loud, share your thinking process with your recruiter, and work towards a solution in a paced gradual manner.

  2. The Technical Section is Only Part of the Process
    Candidates tend to focus on the technical aspect of the phone interviews. Remember, you are just as likely to be disqualified for interpersonal reasons as failure to answer technical questions. Be forthcoming, friendly, enthusiastic, and communicative. Ask questions about the company, its values, and its culture.

  3. Remember Your LinkedIn Profile and CV
    Your Interviewers at SIG will likely ask about items on your resume and possibly even your LinkedIn page. Be ready to talk about your experience and prepare to share past success stories with your interviewer. Consider styling your responses using the STAR Method.
