Applied through a recruiter. We had a 45-minute phone screen with the Head of Performance, followed by a 2.5-hour online coding test on codility.com. Then came the first on-site interview: two people at a time, with three rounds of interviews, each lasting 30-45 minutes.

My experience was in C, so they asked me to come back for a Python on-site coding test. After that, I had two more interviews with another manager and HR, and lastly, one with the CTO.

They did a fairly good job in the process. I'm just disappointed I didn't get an offer. :)

Standard software and networking questions. And also, for the second interview, parse text data in Python to find average trading processing times on-site. Had 1.5 hours to do it, left in an office with an internet connection.

Give a 5-minute presentation on any topic to us, pretending to be a 3rd-grade audience. It is timed, and then after, will write down what was communicated and what was trying to be communicated and compare them.
