Full Stack Developer Interview Experience - Seattle, Washington
Process
It was a pretty straightforward process: one initial call with the HM and one onsite. The recruiting team was really helpful as well, so it was an overall good experience.
Questions
So many random theory questions on Java, SQL, and frontend parts. A small design question. Four engineers interviewed me. It was a one-hour round, and there were back-to-back questions, which was a little overwhelming for a new grad.
