Discover interview questions

It was a very long but enjoyable/easy interview. I loved the managers and they made the interview feel more like a conversation. Technical questions focused on real world implementation rather than obscure made-up problems. However, after receiving good feedback from the recruiter, he promised to get back to me by a certain date… he then reached out to push back that date by 2 days… then never contacted me again. I have no idea what happened but this left a very bad taste in my mouth. I won’t be applying to Discover again.
