BlockTech (Netherlands) interview questions

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.

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.
