First OA followed by 30min behavioural. After that there are 3-4 rounds of technical questions and one final behavioural. Did not make it pass the first behavioural. Questions about your projects, CV, why Optiver, etc. Even though I thought I did well, they told me they were looking for somebody whose experience more closely aligned with the role (why interview then? Also, it's a graduate role).

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.

Pregunta 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

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