I applied through a staffing agency. The process took 8 weeks. I interviewed at Optiver (London, England)
Interview
Long interview process:
1)Recruiter telephone chat
2)Multiple choice exam
3)Technical round with senior designer
4)System design
5)Trading system design
6) project deep dive
7) meet the team and CTO
The recruiter was very unprofessional and badly represented the company.
I passed stage after stage but never got a reply after the last stage. This is an arrogant company that wastes the time of their candidates. They want someone in Amsterdam and make political difficulties for people applying for posts in satellite offices. Interview was technically very easy. Very little transparency with an unfriendly engineering team. The engineering team is comprised of many low experienced and technically weak members. Not a great place for someone who wants a top technical role and progression.
There was a hacker rank interview in the first round. The hacker rank interview took about 2 hours. I think there were about 30 questions. They were low level FPGA questions.
I applied online and got invited for the online assessment. OA was a 60 minutes exams with multiple choise questions and RTL code debuging, and mostly basic digital logic questions. still waiting for the result.
I applied online. I interviewed at Optiver (Amsterdam) in Jan 2026
Interview
I just did the first assessment and it was about multiple choice questions and a coding question in c and a debug questionin verilog. Most of the multiple choice questions were about logical gates and truth tables
