Candidate interview experiences
First-hand accounts from people who interviewed at Citadel.
Data Analyst
I had a frustrating experience interviewing with them. It involved multiple rounds of interviews and a take-home assignment. However, they completely ghosted me and never responded to any of my follow-up emails. The lack of communication and disregard for candidates' time is disappointing and unprofessional. This left a lasting negative impression.
- Were the first rounds mostly behavioral, and the later rounds mostly technical?
Data Analyst
First, there was a Business Development round where they asked behavioral questions. Second, there was a verbal case study. For this, I was given an investment scenario and asked what types of alternative datasets could be explored for that investment.
- What drives your career choices?
- Tell me about your experience using alternative data or similar data for investment purposes.
- Could you give an overview of your resume?
Data Analyst
A Citadel recruiter hit me up on LinkedIn. First, I chatted with the recruiter about my experience and if I was a good fit for the job. Then, I took a HackerRank test, but unfortunately, I didn't pass because I didn't finish all the questions on time. The test had two SQL questions and one Python question that was broken into three parts. I got all the SQL done and two parts of the Python question, but time ran out before I could finish the last part.
- Can you write an SQL query to fetch entities related to given IDs?
- Write an SQL query to find the average price for specific IDs.
- How would you clean data in pandas by filtering out rows that don't meet certain criteria?
