Fetch.AI Machine Learning Engineer interview questions

A recruiter contacted me for the position. The interview was with two engineers from the company one was working in NLP another was a Python developer. The interviews were polite however they were not prepared for the interview. I felt that they did not understand the latest developments in the field as they were junior engineers and were mostly doing implementations and not actual research and model building. I never for any feedback from them. The recruiter also did not respond my feedback request.
