Superhuman IOS Engineer interview questions

A recruiter reached out to me on LinkedIn regarding the role. I sent her my resume and we scheduled a call to discuss the position and my experience. The role is remote first and there's an office in the city I currently live in however I was told I would be required to move to SF. I would be working remotely from SF but would need to come in to the office 1-2 weeks a quarter. I found it very strange that I would need to move to work remotely but continued with the process. I was then given a technical interview which was HackerRank which was fine but got tripped up with the math. I was rejected after.

HR Interview, pretty standard 30 minutes. Getting to know each other. Interview with Engineering Manager: Work practices, interaction and communication with teammates, ways of working. Was very friendly and approachable. Technical Interview: Small introduction about team structure. Questions about Swift Development Language along with iOS General Knowledge. Followed up with Leetcode
