I applied through other source. The process took 2 weeks. I interviewed at Optiver (Chicago, IL)
Interview
The first step in the interview process was a brief phone call discussing the experience and projects I listed on my resume. Then I was directed to take an online coding test that had several questions ranging from fairly easy to more challenging.
I was invited to interview at their offices. There I experience a mix of behavioral and technical interviews.
Interview questions [1]
Question 1
Write a function that parses an input string that contains the representation of the nodes of a binary tree in the form "(a, b) (c, d), ..." where each pair represents a node. The first value in the pair is the parent of the node, and the second value is the value stored at this node. The function should handle any errors with the input or the tree including improper input format, too many child nodes, and cycles within the tree. If there are no errors, the function should cycle through the tree and print the values of the node in order.

Interview

Not too bad, behavioral and technical stages. They start of with a behavioural and resume review, this is after you pass the OA ofc. Then after passing that they give you a technical.
Interview questions [1]
Question 1
What are some extracurriculars you have done, how do they relate to your growth and interests.
Includes OA with usual math and cognitive tests. The technical interview involved a 1-1 Zoom call with their trader, where you are playing betting games on their assessment platform. The interviewers are very nice and willing to help, even if you get stuck and have nothing to say.
