Applied online, and then had a telephone interview. The telephone interview was very straight forward. They asked me about my CV, course material and about why I choose First Derivatives. I then got invited to an interview at their Newry Office. This lasted all day and consisted of two different interviewers seeing you separately. There seemed to be confusion as I was being interviewed for Software Engineer but my telephone interview I was being interviewed for financial Engineer. They asked more in depth questions about my CV many of which were repeated. The experience I had with one interviewer was very relaxed but they basically told me that the company will be acquired within the next few years ( which in turn means there might not be any future career aspect). Overall it was a good interview, nothing was too technical but the real killer was the aptitude test at the end. You were given exactly an hour, and not a minute over, and the questions were completely different from any I have had before.
