I had applied through their Careers page for the role of SWE Intern. I got a call from them to schedule my interview. After two weeks later, my interview took place over phone. HR was very friendly and answered all my emails very patiently. Overall I had a very good experience. I think I got rejected due to my poor way of explaining solution to the engineer!

Quite a competitive process, as expected. You need to be well-prepared, but not really unreasonable. May take awhile to receive a response as I know a few people who waited months even for FT.
