I applied online. The process took 2 weeks. I interviewed at Susquehanna International Group (Philadelphia, PA)
Interview
Applied to the job post on-line and got a phone call from HR three days later. 10 days later got a phone interview with the tech manager for 1/2 hours. The on-site interview was 3 hours long. Interviewed by a 2-person group of hardware engineers, then by another 2-person group of hardware managers, then by 1 software engineer, and by manager. They asked many technical and behavior questions.
3 part interview. Phone screening with initial basic questions. Detailed technical phone interview. Final step is onsite for a day with the team. Overall good process and I think they do a nice job of screening for talent.
