I applied online. I interviewed at Jane Street (London, England)
Interview
Telephone interviews that lead to in office interview. The interview was mainly testing math and probability knowledge, with plenty of brain teasers. There was no question about my background or anything like that.

Question 1
Consider a list of all the integers from 0 to 1000000. What is the sum of all the digits of these numbers?
Heard Jane Street has exciting internships for female students so I decided to apply. Filled out online application. Received a response for online assessment. The assessment was quite difficult for me. The interview was even harder. Lots of technical questions.
