All Bloomberg rounds

Bloomberg · Software engineer · All levels

Technical Phone Screen (Live Coding)

Brief intros, maybe one warm-up question, then straight into 1-2 DS&A problems in a shared editor

What this round is judged on

  • Problem solving · reaches a correct working solution
  • Communication · thinks out loud and explains the approach
  • Complexity analysis · states time/space cost unprompted
  • Edge cases & testing · handles boundaries and tests own code
  • Code quality · clean, readable, idiomatic code

What happens in each stage›
Online Assessment (HackerRank)
Timed DS&A coding, typically 1-3 problems in roughly 60-90 minutes. Standard for new-grad and intern pipelines; sometimes waived for experienced or referred candidates. Whether a given candidate gets an OA vs. going straight to a phone screen varies.
Recruiter / HR Screen
Logistics, background, level fit, and motivation. Bloomberg recruiters probe 'why Bloomberg' early and seriously.
Technical Phone Screen
Usually one round (occasionally two), ~45-60 min live coding in a shared editor (HackerRank CodePair / CoderPad-style). Pure DS&A, Easy-Medium, with escalating follow-ups on complexity, edge cases, and testing.
Virtual Onsite (Final Loop)
Typically 2-3 technical rounds plus a behavioral/motivation component, ~45-60 min each. Composition varies by level: new grads see coding-heavy loops with a Bloomberg-style object-oriented design round and little/no system design; senior candidates are more likely to get a finance-flavored system design round.
Decision & Team Matching
Bloomberg has historically interviewed candidates generally and team-matched afterward (a hiring-pool model) rather than for one specific team, though some teams run direct loops. Persistence of this model into 2026 is unverified.
