I applied online. The process took 1 day. I interviewed at Optiver (Singapore) in Oct 2023
Interview
Did online assessment, coding knowledge assessment and a zap quiz. Fun experience, expect take quite a while (a few hours) to complete all assessments. But i believe you dont have to finish the different tests in 1 seating.
Interview questions [1]
Question 1
Knowledge quiz included scheduling algorithms, computer networking, operating systems knowledge and some basic data structures and algorithm qn. They are mcq questions.
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.
