I applied through other source. I interviewed at DataSocket (City of London, England)
Interview
The interview was conducted over zoom with two interviewers - a junior and senior analyst. A couple of introductory questions with the rest of the questions being technical.
A lot of the questions were worded poorly, and asked in a deceptive manner in that they were trying to see if you'd make a mistake.
Interview questions [1]
Question 1
There is a game where a fair coin is tossed. If the coin shows heads the initial bet is doubled and if tails, the initial bet is halved. If the initial bet is $2, how much would you pay to play this game?
