I had one round of OA, and then one round one-hour technical interview. The arrangement of the interviews were efficient. Got reject after the technical interview although I answered the questions fine in my opinion.
Interview questions [1]
Question 1
Option pricing, direct calculations and implementation. Lastly a standard proof questions using optional stopping.
I interviewed at BlockTech (Netherlands) (Amsterdam)
Interview
Very friendly initial 1-on-1. Got to meet some of the people there. Messed up the first technical task that had to be completed in 4 hours. A bit stressful as a process.
I applied through a recruiter. I interviewed at BlockTech (Netherlands) (Amsterdam)
Interview
First had a 3 hour maths screening test, then short interview on brainteasers and probability, then slightly longer technical interview (probability, some coding too). Recruiter responded very quickly after each assessment stage.
