They have been extremely successful over the last few years and experienced rapid growth. Just check publicly available financial statements on the CompaniesHouse website in the UK to see the growth in revenue and number of employees.
They are flying a bit below the radar compared to more famous competitors but I would rank them as one of the top quant firms at the moment.
Growing pains due to expansion, office moves, facilities issues, and other factors have been quite distracting at times, as we are suffering from success.
Applied via recruiter. First stage was a phone call with a software developer. Not a standard interview at all -- was given a huge C++ code using a library I've never heard of and I was asked to fix it.
Two technical screenings. The interviewers were very nice, and I felt at ease during the interviews. The content was challenging but manageable, and they were very happy to help when you got stuck.
Two technical interviews followed by a take home test, they did not proceed further. Overall seemed friendly, although did not get feedback on the take home, which was pretty lengthy and required most of my weekend.
