Candidatei-me online. Fiz uma entrevista na empresa Optiver.
Entrevista
Shortly after I applied, I got invited to complete a series of tests: 1. Zap-N test - 9 neuro-assessment games that tested various elementary memory, logical, decision-making, and math skills. You have a tutorial/trial phase before every game; use that phase to plan the strategy and discern whether time is a factor. 2. Hackerrank test - which contained a series of SWE questions related to data structures, operating systems, networking (a lot, with a focus on protocols), and coding in general. Following the completion of the test, you are asked to solve two very poorly worded coding questions of leetcode medium and hard difficulty (hard to say). The medium question was a hashmap question related to trading, while the hard one was an interval question that I believe is solved using PQs and maps/segment trees. Afterward, I got invited for an HR interview. The interviewer was very nice, and the interview was enjoyable. The questions were mostly about my projects/experience and plans for the future, along with a few questions about Optiver. I got rejected afterward. The whole process was very expeditious.

Pergunta 1
Tests: Neuro-assessment games Data Structure, OS, Networking, and SWE questions 2 coding questions; hashmaps, and intervals HR Interview: Past projects/experiences and future plans Optiver (e.g. What is a market maker?)
The interview process began with a rigorous online assessment designed to test technical proficiency. It focused on core engineering principles and problem-solving skills, providing a challenging yet straightforward initial evaluation stage.
Coding + tech knowledge screen + puzzle round.
Behavioral (recruiter round).
Then 4-5 successive coding/system design rounds, followed by a final behavioral interview round with a tech lead + recruiter.
Technical OA mixed with random games and knowledge test about a variety of topics into a behavioural interview where they ask you a few questions about the role, your motivations and interests.
