Bloomberg Software Engineer Internship interview questions

The interview took an hour. They spent 15 minutes asking about my resume and then 45 minutes on a technical question. They asked to write a program that could identify if the delimiters in a string were balanced

I was contacted through linkedin and had an initial call with the hiring manager. The technical interview followed after this. I was asked technical questions about my CV and then we proceeded to the coding portion of the interview where I was asked a Leetcode easy question and then asked to optimise it. Interviewer was very nice and friendly
