Rain Instant Pay interview questions

Cool company and nice people, but the interview process wasn't stellar. Multiple rounds, not one interviewer had reviewed my resume before speaking with me. Didn't feel mutual - just answer questions, jump through tech hoops, and move onward to next round. Never discussed role specifics, comp band, culture, etc. Once you've made it through 3 rounds, they'll invite you to an onsite. The onsite is a challenging is more challenging than most FAANG interviews - one hour system design and an hour to go implement the system you just designed after.
