I applied online. I interviewed at Block (Vancouver, BC) in June 2024
Interview
Irrelevant mathematical technical question was asked.
The interviewers assumed I knew the formulas on Probability and asked a coding question without providing any formulas, even after I asked. Although I knew the basics formulas, one for calculating a required total was not given and I could not get the right answers even after I asked the interviewers to provide the formulas.
It seems like the interviewers didn't even prepare and know the material that they are asking.
Interview questions [1]
Question 1
Calculate the probability of a team winning after playing a number of rounds.
Inital take home, followed by extension interview, followed by a coding challenge, followed by system design interview.
The whole process took 3 months!
The interviewers are usually really nice and want you to do your best.
The interviewer was nice, and he is friendly and willing to give hint, the question has 2 follow-ups, it was hard to complete in time. The question was not a typical LeetCode
Phone screen and then a full day of interviews. 3 pair programming challenges, a system design review and a prior experience interview. There was also an onsite lunch with a person from the company.
