I applied online. I interviewed at Susquehanna International Group
Interview
First round was 30 minute call with HR, they asked in details about your experiences listed on your resume & past projects. Second round was 1.5 hr interview with 2 software engineers. I was given code and was told to spend 30 mins optimizing it. The optimization involved hashmaps. Afterwards, we had to discuss the optimizations made and why it worked. There is a superday after this 2nd round but I did not make it.

Tell me about the most challenging technical project you have worked on.
I interviewed at Susquehanna International Group (Sydney)

OA (code signal GCA, 4 questions 70 minutes) -> Recruiter call (30 mins) -> 90 min technical screen. Presumably after this point would be onsite/in-office interviews but didn't make it there.
Had to do work in Python in a live interview session. Talked with hiring manager about resume. Overall it was not too bad. The interviewers were nice throughout the entire process.
