Marshall Wace Software Developer interview questions

The second stage consists of several programming challenges (6 in total) - and 4 multiple choice questions. The questions require skills with file reading, input management and some systems level thinking, so Leetcode alone is insufficient. They warn you that some questions cannot be solved in your language of choice, but don't worry about learning a new language, those questions are more 'deciphering code' questions - you aren't really ever asked to code in a language that is not of your choosing.

Algorithmic question coded live with 2 people on the call. Interviewers not very supportive and aloof, even though I did pretty well with the task the interview was cut short for unknown reasons.
