Questions were mainly just about my experience with the technology. Issue happened after the fact when they wanted a portfolio of my work including source code, which I cannot give from my former company. I sent a well thought out email with screenshots showing my work, explained I cannot give them source code, then they ghosted me. Extremely unprofessional to not even respond to a well thought out email. If side projects are a requirement for the job, the portfolio of work should have been the first step in the interview process to save us all time.
