I applied online. The process took 2 weeks. I interviewed at Optiver (Sydney) in Apr 2022
Interview
The interview consisted of a lot of rounds. It starts off with a resume screening, followed by a general ability test. Then there is a code screen, which is followed by the behavioral. Usually the behavioral is considered to be one of the hardest rounds for Optiver. If you make it through, you go to a pair programming round which is followed by the Final Day interview. The final day interview has 3 components: 1 Behavioral 2 Technicals. The technicals test your understanding of data structures, algorithms and object oriented design.

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
