I applied online. The process took 4 weeks. I interviewed at Optiver (Sydney) in Mar 2019
Interview
The interview process was great. They were very fast and efficient about arranging the next steps and gave constructive feedback at each step.
First there is an online test (~ 2 hours).
Then a behavioral phone screening interview, followed by a technical phone interview.
After that it the final on-site interviews.
I got through to the final round of on-site interviews, which consisted of a technical and behavioral interviews.
The technical interview was difficult and I bombed it a bit.
Overall, it was a great experience.
I applied online. I interviewed at Optiver in Feb 2026
Interview
As soon as my CV reached them, I had 7 days to complete a HackerRank and 2 more tests. It took them from Monday morning (when I submitted the coding test) to Wednesday evening to reply.
Interview questions [1]
Question 1
Was a Hacker Rank average but difficult, then a CS questions in multiple choice and finally some kind of minigames.
After I applied, I received an online assessment shortly. It was hacker-rank styled. I had only 2 choices of language - C++ and Java. A bit difficult than average, but doable with a lot of practice.
The original assessments consisted of:
- A coding test (1 hard question) which takes approx. 75 minutes
- A coding knowledge quiz
- Zap-N, a set of short neuro assessment games

Question 1
The coding test question was very difficult. Required a great understanding of data structures in programming and problem solving
