Bloomberg Software Developer interview questions

Applied online, got invited to a phone coding interview with one of their engineers. The phone interview consisted of 2 easy coding questions for which you would code live, the analyse your solution’s complexity using the big O notation, think about improvements. Next, I had a video interview with two engineers, which followed the same patterns as the phone interview. The only difference were that the questions were more difficult. The examiners provide hints, but mines were not great at doing so, or communication in general. Got rejected afterwards, we didn’t have the best interaction.
