Bloomberg Sr Software Engineer interview questions

few technical rounds and Hr preparation call for the next stages, at each stage they explain what's coming to make sure you are well prepared in my case the last technical interview wasn't 100%, it took me a while to figure out one of the problems and for them that wasn't acceptable I think its kinda harsh to not accept the candidate for only one question which wasn't perfect but was good, but anyway the general experience was great and the feedback at each stage was so helpful which is something that you don't see at most of the big corporates I hope in the future to get the chance to interview again with Bloomberg
