I applied online. The process took 5 months. I interviewed at Optiver (Sydney) in Dec 2014
Interview
I submitted an application at the beginning of October and I received a phone interview before christmas. After waiting for nearly 3 months, there was no response. So I called Optiver to confirm the status of my application. Then I was told that I can't move to next step. I really think that was just an excuse and the real reason is the hr forgot my thing so she had to say sorry to me to cover up the truth that she had made mistakes.
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
