I applied through a recruiter. The process took 2 weeks. I interviewed at Interactive Brokers (Budapest) in Sept 2022
Interview
A short discussion about what challenges you encountered in software development and how you solved them. This was followed by solving a python problem in codility. Overall it wasn't that hard, you have to know the basic python syntax and cannot google anything.

Question 1
What challenges you encountered in software development and how you solved them?
I applied through other source. The process took 3 weeks. I interviewed at Interactive Brokers in Aug 2021
Interview
1. Online assessment.
- It started well--I solved all 3 coding questions and 90% math questions.
2. Technical Interview
- They asked me a few coding questions + some python related questions. I performed good and went to the next round.
3. Next round...
I expected questions about Python, some coding questions and maybe some elements of system design. But, instead, they asked me a lot of math questions. And I just was not prepared. There was nothing about math in the job description!
The most disappointing thing was that my recruiter told me nothing helpful about the interview process.
So, I had negative experience, and not because of engineers that interviewed me, but because the job description didn't match the actual questions, and my recruiter didn't tell me what to expect.
