Bloomberg's AI coding interview: 30 minutes on a huge Django codebase, still rejected

A Reddit r/leetcode post (shared by dotey) recounts failing Bloomberg's second-round AI codebase interview in London/Frankfurt: Django, an unfamiliar huge codebase, only 30 minutes of coding after a behavioral round. Key points:
- AI-usage boundaries were vague — interviewers never said how much AI is acceptable; using planning and ask modes feature-by-feature passed some tests but still got rejected.
- Reading AI-generated output while simultaneously communicating with the interviewer is "borderline impossible."
- Unlike LeetCode, half the time goes to just understanding the codebase and locating the problem; one-shotting with a single prompt also gets you rejected (the author's friend tried).
- Conclusion: for those celebrating the end of LeetCode, AI interviews are harder and there's no consistent strategy.
