I applied through an employee referral. The process took 1 week. I interviewed at Jump Trading (London, England) in Jun 2021
Interview
Online codility, 1 leetcode hard (KMP string matching algorithm) and 1 awful code commeting question for a regex parser ( python cls vs self, inheritence, ittertools, etc )
Rejected at this stage, I know some people get 2 algorithm questiosn so I will try again next year and hope to avoid the code commenting question.

Interview questions [1]
Question 1
HR call: Talk about your resume, focus on your projects. Hr will introduce jump and inquire about your basic information.
overall was a very hard process and highlyt echnical. requirement to understand programming concepts extremely well, and need to verbalise thoughts in order to walk the interviewer through yr thinking. also have an expectation to be correct and yet fast.
One of the worst interviews I had in my life, the interviewer was doing his own job during the interview and did not even try to hide that. He tried to ask a leetcode hard question with less than 30 min left, testing you if you can memorize the answer.
