I applied through a recruiter. I interviewed at Two Sigma (London, England) in Nov 2016
Interview
1. HackerRank (algorithms)
2. Phone Interview (Background, soft algorithms (easier than HackerRank), probability and stats)
3. London office (4 1hr interviews, 2 completely softdev + as much maths as they could do, 2 --completely-- data science (but no statistics i.e. find the hypothesis in the data not the other way around) and maths/teasers showing up + Surpises
4. NY interview (7 interviews, 2 completely algos, 1 maths/brainteaser, 1 only about data sources, 2 motivations and business ideas, 1 pure HR)
In general more data science and modelling aptitude expected in London, more engineering and ideas expected in NY.
after i upload the resume, I get the online assessment 2 weeks after. The. oa is typical question before. After i finished the oa, i got the 1st round interview approximatly 1week after.
I applied online. The process took 3 days. I interviewed at Two Sigma (New York, NY) in Apr 2026
Interview
OA: 3 coding questions
One question is about the interpolation
One question is about the temperature
One is about regressions
3 questions need to be done within 105 mins in total
After I submitted my resume for the position I applied for earlier this week, I ended up receiving the technical coding test invitation very quickly and without any delay whatsoever from their human resources department.
