I applied online. The process took 2 months. I interviewed at Susquehanna International Group (Dublin, Dublin) in Dec 2011
Interview
My first interview was on the phone with a member of HR. She asked me basic questions about myself and about 4/5 probability questions. I got a call within the week to offer me a second telephone interview. This one was with a trader so was after the working day and took about 45 minutes. Got asked about 6 probability questions and talked about my cv. Got offered a final on site interview. Apparenty it lasts an hour and a half which the same structure as the last two.
The interviews are tough and stressful but there isn't much preparing to be done. The interviewers were lovely.
