Optiver Test

The Optiver Test (or the Optiver Assessment) refers to five online assessments used by Optiver to screen candidates for trading and research jobs. They include four cognitive sections and one personality section. The most famous section is the Optiver Maths Test.

The Optiver Test is notoriously tricky and challenging, as Optiver aims to recruit only the best. You will be facing off fierce competition.

The cognitive tests are primarily focused on numerical ability. The Optiver Mental Maths Test in particular is built to evaluate your ability to complete numerical tasks in your head as quickly as possible. For this reason, calculators are not allowed on the Optiver Test.

The Optiver Test includes:

    • 80 in 8 (Optiver Mental Maths Test)
    • Optiver Zap-N
    • NumberLogic (Optiver Sequence Test)
    • Beat the Odds
    • Optiver Zap-Q
  • Note: some Optiver candidates are asked to take the SHL Verify G+ assessment. We have a separate page about it.

Let’s take a deep dive into every one of the five Optiver Test sections:

Optiver 80 in 8 Test, AKA the Optiver Maths Test

The first obstacle on your journey to joining Optiver, this test is exactly as it sounds: 80 arithmetic questions in 8 minutes. It is also known as the Optiver Numerical Test or the Optiver Maths Test and is characterised by a pressing time crunch.

Regardless of how good you believe yourself to be, we advise against taking the Optiver Maths Test without practising beforehand, as it will be a shame to find your candidacy terminated after the very first assessment.

Being able to perform mental arithmetic is important in trading roles, as you will be required to make split-second decisions regarding financial instruments. This is what the Optiver Mental Maths Test is designed to assess.

Let’s take a look at a few examples from the Optiver Numerical Test:

The scoring for the Optiver 80 in 8 works as follows:

You will be awarded a point for every question answered correctly. A point will be deducted every time you answer incorrectly or skip a question. A passing score is higher than 55, but you’ll want to achieve around 70 or above to stand a chance.

Optiver 80 in 8 is a multiple-choice test, so the elimination of obvious wrong answers may be a good strategy, but being able to do the maths is the best path to success. Make sure to practise your mental maths: addition, subtraction, division, and multiplication with whole numbers and fractions up to 2 decimal points. Additionally, basic algebra is needed.

Optiver 80 in 8 Practice

The Optiver 80 in 8 is a challenging task, especially when your competition tends to be no less mathematically apt than you. Finding an accurate platform to practice Optiver Maths Test questions can make a lot of difference. 

You can find that, as well as study guides and test tips, all included in our Optiver 80 in 8 PrepPack. We offer an accurate simulation, as well as practice tests that build your mental maths skills gradually and expert advice that will come in handy on the real test. 

What is the Optiver Zap-N Test?

This hour-long assessment consists of nine games, ranging between two minutes to 15 minutes each. These games assess a variety of cognitive skills and abilities. 

Using a computer with a mouse is recommended, but the system asks you what controls you are using (touchscreen, trackpad, or mouse) and takes this into account when calculating your score. 

Attitudes towards the Zap-N among Optiver test takers vary.  

On the one hand, games are lighter and more fun, as compared with the Optiver maths test. On the other hand, it is not always clear what these games have to do with being a trader, and candidates are often frustrated after being rejected due to a seemingly banal game. 

For this reason, it is a good idea to take the Zap-N seriously. Sit the assessment when you are feeling sharp and alert, just like any other part of the Optiver Online Assessment. 

Unfortunately, we don’t currently offer Optiver Zap-N practice. However, we are working on it! Until then, here is a rundown of the Zap-N games, so you can be mentally prepared for what you are about to face: 

The Optiver Sequence Test

If you’ve made it this far in the process, you’re doing quite well.

The next step is all about number patterns. On the Optiver Sequence Test (officially known as Optiver NumberLogic), you will be shown sequences and asked to identify the pattern and predict the next number.

The difficulty level rises with each sequence.

Tip: As with the other Optiver tests, particularly the mathematical ones, there is no substitute for practice. However, it is usually worth starting out by calculating the difference between adjacent numbers and looking at the ones digits.

The Optiver Beat the Odds Test

By even reaching this stage you’ve already beaten the odds. However, the title of this Optiver test refers to probability. This test requires not only reflexes and quick thinking, but also knowledge and understanding of probability theory.

The questions on Optiver’s Beat the Odds are timed, as is the entire. In 15 minutes, you will need to answer questions pertaining to probability theory. It’s likely you’re familiar with the basic concepts of probability if you graduated with a STEM degree. Still, we recommend going over the material, and answering questions from your old textbook, or any resource you can find online.

We are working on a Complete PrepPack for Optiver Test practice, which will include practice questions for this section.

The Optiver Zap-Q Test

The final test of the Optiver Online Assessment, this one is all about your personality, traits, and inclinations.

If you have built up muscle tension from the stress of the last four tests, you can take a deep breath and ease up for this one. You will be asked questions about yourself, and your answers will be processed into a comprehensive personality profile that your recruiters at Optiver will see.

Don’t be fooled, though.

Just because this Optiver test is easier, doesn’t mean there are no stakes. Your answers will be important during the interview stage of your Optiver hiring process. Be authentic and genuine but remember to present your most professional self. Your recruiters don’t need to know what you are like in a family-and-friends setting. They need to know that you are reliable, capable, and in line with company values. There are wrong answers.

Want complete and comprehensive practice for the Optiver tests?

Our team is working on it. At the moment, we offer prep for the Optiver mental maths test (80 in 8) and we hope to expand this in the future. If you have questions, thoughts or suggestions regarding what a complete Optiver Tests Preparation Pack should look like, don’t hesitate to contact us.

Optiver Test General Information

Here are some important things to keep in mind ahead of the Optiver Test:

  • Depending on how you applied, some of the tests may be taken online through Skype or a similar platform. You will receive all the information you need from your recruiter. Contact us if you are not clear on any of the instructions, and we’ll help you figure them out.
  • All five sections typically take an aggregate of two hours and 45 minutes to complete.
  • If you fail any of the sections, you will not move on to the next one.
  • If you pass one section, you will be able to pause for as long as you like before starting the next test. You cannot pause mid-test.
  • There will be a time limit to complete all the tests, usually 3 days.

What comes after the Optiver Online Assessment?

There are three steps following the Optiver assessment, which you have to complete before receiving an offer.

The first is an HR interview. You will speak telephonically with an HR representative from Optiver who will ask you questions about yourself and invite you to ask questions about the company.

Secondly, you will go through the technical interview. This is another phone interview, but this time – you will need to demonstrate your knowledge. You will be asked to answer questions and solve problems that pertain to the position you are applying for. The important thing to know is that less importance is placed on right and wrong answers, and more on your thought process and perseverance in the face of a challenge. To get through this stage, brush up on your knowledge and approach it in a calm and relaxed manner.

Lastly, there’s the Optiver Interview Day. Just like its name suggests, this is a full day of assessments and interviews. You will have to clear your schedule and travel to the chosen Optiver office. Optiver has been doing this for years, and they will take care of accommodation and travel expenses.

For aspiring traders, the interview day consists of another technical interview, another HR interview, and a competitive group assignment – a market-making simulator. This day is also a great opportunity to meet your potential coworkers!
