This summary is an attempt to shed some light on modern quantitative trading since there is limited information available for people who are not already in the industry. Hopefully this is useful for students and candidates coming from outside the industry who are looking to understand what it’s like working for a quantitative trading firm. Job titles like “researcher” or “developer” don’t give a clear picture of the day-to-day roles and responsibilities at a trading firm.

What are some common coding interview questions that can be answered (better) using the sliding window technique?

The science of extracting meaning and learning from text data is an active topic of research called Natural Language Processing (NLP).
