I applied online. The process took 3 months. I interviewed at Mars (Leeds, England) in Jul 2019
Interview
After two remote interviews they invited me to come to the office and bring a presentation with me. Coming their I had to prepare two panels of two different cases, and than present my own presentation. Was very difficult considering it is a job interview. It took almost 4h
I applied through university. I interviewed at Mars (Rochester, NY)
Interview
When I was interviewed there were about 3 people that were interviewing me. There were no technical questions but rather questions on how you organize your time. So be prepared on questions on your work ethic and what you can do to be better.
