Stripe Infrastructure Engineer interview questions

Started with an email with the recruiter, who forgot to respond to schedule our phone call. After scheduling the phone call, we spoke for 30 minutes and scheduled a 45-minute pair programming exercise over Zoom. I interviewed in Scala and was told that the only thing that mattered was correctness. Although simple, I struggled with the interview because the expected solution is not idiomatic Scala. My interviewer also admitted that his Scala was rusty.
