I had a intro call with a recruiter who then sent me some possible roles. I expressed my interest but then never heard back from them. Essentially, I was ghosted by a recruiter , not a very pleasant experience.

First I was contacted by a hiring manager and we set up an appointment with an engineer in the field I would be working in. Then I was contacted a few days later by the appointed person. He asked me various questions about previous experience I had listed on my resume, some data structure and algorithms questions.
