Contacted the internal recruiter, after weeks of delays, he responded with "requirements have changed" and requested experience not with WP but with some small js frameworks. After I confirmed the experience with these, he responded with the "requirements have changed we no longer interested in WP". My own recruiters told me that they wanted somebody with WP plastered "all over the resume" with lots of years of experience, exactly what I have. I even submitted WP portfolio with active e-commerce sites. I also was told by my recruiters that they tried to fill this role for long time, now I know why - they don't really need anyone. Waste of time.
