GP Energy Management Software Developer interview questions

I was connected to this company via a third-party recruiter. Upon my request, a phone interview was rapidly arranged for the same day for which I was thankful. The call was expected to last 45 to 60 minutes. Their tech stack for this role included Python 2.7, Django, and Celery. I terminated the interview after I learned that they don't focus on renewables and they no current plans to move to Python 3. This may be okay for them, but it's not okay for me. I don't need to burden myself with using obsolete technology all around.
