How do you keep up-to-date on new technologies and trends in this industry?

One way a potential employer will gauge 'fit' is by ascertaining to what extent you keep up with the fintech industry. While you may not need to be a crypto expert yourself (this will depend on how technical the role is), you should show a basic understanding of the fintech sphere as it relates to the role. Demonstrate to your interviewer that you keep up with the industry through membership in industry-relevant groups or publications. You should have a reliable news outlet that you rely on for industry news, which you can mention to your interviewer.
