Nureva interview questions

I was contacted by a recruiter to set up a phone screen. Typical HR phone screen asking about experience and expected salary. A week later, they told me they wanted to schedule a 90 minute phone screen the next week. The technical interview was straight-forward, with a few questions about my experience and an easy Leetcode problem. The hiring manager assured me that he would like to schedule further interviews and ended the meeting after 60 mins. Over a week later the recruiter rejected me. About 3 weeks total.
