Bloomberg C++ Developer interview questions

Applied online got an email then telephone interview along with hacker rank test. First he asked about my CV briefly with emphasis on why you chose Bloomberg then he started coding questions

The initial interview was an HR screener who sounded me out on what my skills were and what I had worked on. This was followed by two technical phone interviews using HackerRank to pose several questions for C++ in first, with 3 topics, then a bit of SQL coding in the second, with a lot of discussion of DELETE of nonunique rows in a table and SQL tuning
