Who is a quant analyst?

A quantitative analyst or a quant is a person who specialises in the application of mathematical and statistical methods to understand and predict the behaviour of financial markets. Quantitative analysts aim to represent a given market situation in terms of numerical values.

Quants are required to be proficient in the field of mathematics of multivariate calculus, linear algebra, differential equations, probability theory, statistical inference, and econometrics. In addition to this, they should also have knowledge of programming languages such as C, python etc.

Hence, a quant is a professional in the financial technology industry who designs complex algorithms with the help of quantitative analysis.

What does a quant analyst do?

There are various roles that a quant can take up and these are:

• A quant trader/analyst - Designs and implements models for the employer firms to price and trade securities. Also, a quant trader/analyst is concerned with the integral process of risk management.
• Data scientist - Collects, cleans and takes out useful information from the data. Data scientists use skills relating to statistical and machine-learning techniques. A data scientist is equipped with comprehensive data & feature engineering skills.
• A quant developer - They are of two types. One works with the quant analyst to help them optimise their models for implementation. The other does the job of dealing with financial pricing data and trading architecture.

Importance of preparing for an interview

The quant interview preparation is, undoubtedly, helpful to an aspiring quant to imbibe those trading skills which an employer expects from them. After an interview preparation, the candidate acquires the following:

• Confidence to speak and present himself during the interview
• The knowledge required to answer the interview questions
• There is greater success in an interview when one has adequately prepared, compared to when one has not prepared

For reaching the maximum efficiency in each of the above-mentioned roles, a quant needs a particular skill set which we will discuss now.

Top skills for cracking the quant interview

So, what are the top trading skills that an employer looks for in a quant candidate?

After this question is answered, you can learn all the necessary trading skills from algo trading courses and crack the quant interview. Learning trading skills requires dedication, perseverance and determination to achieve your goal of becoming a quant in a financial firm. Once you are through with the learning, you will be prepared and confident during the quant interview.

These top trading skills are:

• Trading experience
• Programming skill
• Statistical analysis
• Analytical skills

Trading experience

The key goal of any financial firm hiring a quant is to reap the best returns by investing when there is an opportunity to maximise profits. Hence, the quant can help with finding when to enter a position and when to exit.

For example, the trader must know how to find the data patterns so as to understand the trend of the market. This is useful in trend-based trading.

The experience of trading in the financial markets helps a quant since the decisions related to the order execution can be taken with good reasoning and know-how.  Also, for a quant to reach and maintain success in their job role, a thorough knowledge and experience with option pricing models, greeks, volatility, hedging, and options trading strategies are required.

Since derivatives/options are highly traded instruments, thorough knowledge of the same is a must.

Moreover, traders must be aware of the market microstructure. The National Bureau of Economic Research (NBER) defines market microstructure as a field of study that is devoted to theoretical, empirical, and experimental research on the economics of the securities market.

Market microstructure deals with the issues such as market structure & design, price formation & discovery, transaction & timing cost, information & disclosure, and market maker & investor behaviour.

Programming skill

Speaking of programming skills, it is a must for any quant to learn a computer language such as Python, C, or C++. Computer programming skill helps the quant to code the trading strategies. Sound programming skills help with backtesting and executing the strategies with increased efficiency, accuracy, and speed.

Moreover, the Python programming language equips a programmer with the ability to use analytical skills and data visualisation skills for helping with the most accurate price prediction. Also, Python helps the trader with low-frequency trading strategies while C and C++ help with the execution of High-Frequency Trading and Medium-Frequency Trading.

Statistical analysis

Statistical analysis is an important part of quant trading. Knowledge of statistical topics such as time series and multivariate analysis is needed in order to create trading strategies and implement effective risk management practices.

The statistical information includes collection, analysis, interpretation and presentation of the data.

Analytical skills

Analytical skills are a must for a quant to be able to use logical and analytical thinking for activities such as price prediction and strategy creation. Also, with analytical skills, the quant can create logical trading strategies.

For instance, with analytical skills, the quant can analyse the historical data with logic and maths and on the basis of the same, a trading strategy is designed.

Some tips

Here are some tips for preparing for the quant interview:

• Make sure you are familiar with the quant job role and the financial firm you are applying for
• Undertake a project work related to quantitative trading initially as an intern
• Practise the mock interviews to make sure you are completely prepared
• You must acquire soft skills such as communication, problem-solving, and time management
• Dress accordingly and be presentable

Knowledge of the job role and the financial firm you’ve applied to

Now this one is quite a basic skill but it helps the quant look serious about the job role or the opportunity. When you have knowledge of the job role and the firm you’ve applied to, it would make it easier for you to answer role/company-specific questions and give an impression that you are genuinely interested.

Soft skills such as communication, problem-solving, and time management

Apart from all the skills we discussed above, one thing that an employer keeps noticing in you from the very beginning of the interview is your soft skills. When answering questions, you should be able to explain your thought process to the interviewer, this is where the use of soft skills comes in.

You must be great at communicating, problem-solving, time management, teamwork etc. for landing the job you want.

Dress accordingly and be presentable

This is an obvious tip but extremely important. Dressing accordingly gives a professional feel to you and makes you more confident. Also, apart from your confidence going up, the employer perceives you as an individual who is serious about the job.
