I applied online. The process took 4 weeks. I interviewed at Instinet (London, England) in Feb 2017
Interview
Two rounds. First round is technical, second round is HR related questions. They are generally easy especially on the HR bit. However, on the technical bit you need to make sure you research well enough what are their products and services. Also helpful to look review job description as it will make you more confidence.
I applied online. I interviewed at Instinet (New York, NY)
Interview
One technical interview (with the person I was to work with) and one with the manager. Focus on Java and Ruby on Rails. Got reply from Instinet in couple of weeks.
