Good fair process, people are nice, interviewers are smart, questions are interesting. Relatively quick turn around time between rounds which is always appreciated and very respectful of competing offers / deadlines.

starting with a mental math test, you will be invited to hr round interview if you successfully pass this online mental math test. hr asked a bunch of standard quant firm hr round questions, about your passion and experience etc. overall the interviews are not that difficult. also the interviewers are nice and experienced.
