1Password Applications Developer interview questions

Went through a referral from someone inside the company. Gave the person that works inside a copy of my resume, LinkedIn profile, and social media links. The recruiter will call you with phone screen questions. Second interview will be with the Engineering Manager for 1 hour discussing your experience, what techstack you know and some question I listed below. No response for 10 days after that and has to follow up with the recruiter just to learn. Even though I got ghosted, the recruiter was very helpful. He has given a very long feedback on what I can improve on and ultimately the reason why you got rejected on the interview
