I applied online. I interviewed at PARTS iD, Inc. (London, England)
Interview
6 hour assessment centre day, first involving 4 hours of difficult numerical tests and maths examinations which everyone attending had to take, and then the afternoon consisted of simulated traded games, and later on those who had passed thus far were invited for panel interviews.
Contacted by someone from HR. The conversation was for 30 minutes. Then about 2-3 hours later I was told to come in for an in person interview. The interview lasted almost an hour. Then three days later I got the offer and accepted
