I applied online. I interviewed at DRW (London, England)
Interview
First round online interview for London's summer quant trading internship.
Some common motivation question like why quant trading, why DRW. And one to two behavioural questions based on CV. A series of probability question.
Did an online assessment followed by an interview with a trader. The interview itself was rather easy and it's the only step before final round so it seems you need to answer perfectly
