Entrevista
The first two rounds of interviews were with researchers. They were pretty nice guys at least it seemed that way during the phone interview. They asked me to walk through my resume first. (Just be confident with whatever you put on your resume.) At the end, you asked simple brain teaser. I failed the third round phone interview with a trader. I got stuck at one problem and that trader lost his patience on me.
