Overall long and exhausting. They start with a tech phone screening. 3 day HW assignment to build a fake web app for Hinge Profiles. Front end in any language you want, they provide some of the backend written in GO. Then another screening to talk about the hw, they'll ask you to scale your simple project to account for millions of users so be prepared to answer that. Last onsite. 4 interviews: Team fit, Backend architecture, Algo, Front-end architecture.
Be prepared to answer questions on scaling up everything.
I gave a negative experience based on the following criteria:
Back to Back interviews for almost 5 hours
Kept through lunch without a break
Algo interviewer gave wrong first case (which effected total algo) and keeps talking to you while trying to solve the problem
Basically, if you don’t really want this job don’t bother.
