bp Summer: Software, Platform Or Security Engineer interview questions

Technical Interview: Started out with basic questions about why you're interested working in BP, why software etc. They then go through a scenario for designing an application and you have to run them through your thought process as to how you would set it up, UI elements, functionality etc. Lastly they had a coding exercise in a language of your choice. For me it was calculating factorials, and they wanted to see several different ways of doing it.
