Pegasystems Technical Support Engineer interview questions

The position is for technical support and in the listing it says experience in Java, C#, or Python required. I have experience with Python, not as a Python professional developer, but I have working projects and I run some simple scripts at my current position. In any case, based on this wording, I thought that would be enough to proceed in a TSE position which I have 3+ years experience in and plenty of strong references. The initial call went well and the interviewer said they were interested in possibly a next step and they would get back with me. Java, Python, C# were not discussed at all (this is important, so please read on). A few days later, I received an email from these this initial interviewer who said she spoke with her HR supervisor and they explained that I would need programming experience. I wrote them back and explained how I run some Python scripts and I can share projects. They wrote back again saying that I would need Java or C# only and it would have to be professional level experience. All of this was very strange and contrary to their job listing, our first conversation, and also the role of a TSE. Please fix your job listing -remove Python as a possibility -explain that years of professional Java or C# programming are needed -change the job title to something that more aptly describes the position. The starting pay of 70k now makes more sense. It would be a good start for a TSE, but nothing to brag about for an experienced Java programmer. I would be wary of this company and their mixed messages from HR. I don't mind being rejected from any position, but I dislike having my time wasted due to poor communication. The situation was overall very strange.
