AKUNA CAPITALMediumNLP00:00Welcome to your interview for the Machine Learning Engineer role at AKUNA CAPITAL.
The question is on your right: Extract Companies and Tickers. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen. You have three graded attempts to score 7/10 or better.
You are building an NLP pipeline that needs to identify company names and stock tickers from financial text such as news, research notes, and market commentary. Off the shelf NER often misses finance-specific forms like parenthetical tickers, exchange prefixes, aliases, and ambiguous uppercase symbols. You want a solution that can reliably tag both entity spans and map them into structured outputs for downstream use.
How would you handle named entity recognition for company and ticker extraction?
