Bloomberg SWE Intern interview questions

Standard. Invited for tech chat then a next round with a senior engineer. Was mostly technical and had to implement answer on whiteboard. Felt like I understood the question and did implement a working solution but only realized at the end they were testing understanding of object oriented and system design principles as well

Two Software engineers asked me about one of my projects, then jumped into coding problem for me to solve within forty five minutes. Was given opportunity to ask clarifying questions for my approach. Got the pseudocode down but not working code.
