Applied originally for a SWE intern position, got shifted to Quant. Interview was set up within days of applying, although the actuall date was about 3 weeks later. The interview was a 45 minute phone screen.
Supposedly 4 phone round interviews, followed by an in-person interview. Made it to the third phone round but was rejected after. First was basic probability and gets progressively harder through the rounds.
