Kymanox interview questions

Initial HR screening, followed by an interview with a manager. Subsequently provided the several contact references requested. Few weeks later, I received a call to communicate a rejection without any feedback and asking if I would be ok to be considered for future openings. However it is concerning that all my references were contacted despite the company having no intention of making an offer at any time. This is extremely inconvenient and likely to prospect potential clients rather than evaluating my candidacy. Contacting a candidate's references is reserved for the final stage of the hiring process, serving solely as a final validation step before an offer is made, and not for unrelated purposes. I was asked to apply for a second position, interviewed again and then ghosted, no feedback received. Lack of professionalism.
