technicals first then behavioural. interview process is actually quite hard. they have current employees interview you but it is a good job. make sure to do leetcode in advance. otherwise it isn't too bad if you are good at leetcode.
Interview questions [1]
Question 1
leetcode medium + hard. behavioural after technical.
I applied online. The process took 1 week. I interviewed at Bloomberg (London, England) in Feb 2023
Interview
On the scheduled date, the interviewer didn't show up. I sent several emails and was ignored. After reaching out personally on LinkedIn, I got another date. But it was clear on the interview day their mind was already made and it was a complete waste of time.
