Bloomberg Intern interview questions

I applied for Software Engineer at Bloomberg L.P. London. I got an interview on the phone and I was writing code on HackerRank. The interviewer was nice and he helped me through the process. I was invited on-site for a second round technical interview. I had to choose the programming language before the interview so they could assign me the right interviewer. Questions were easy: fill an array b with the product of th numbers from a, without the one from the current position.
