Netcracker Technology Senior Business Analyst interview questions

Já fiz 9 entrevistas nesta empresa, algumas delas com a mesma pessoa, em nenhuma delas eu obtive um feedback...continuam me chamando pra entrevistas com início do zero...parece pegadinha mas é um fornecedor de Telecom...hoje não tenho mais vontade de trabalhar nesta empresa, não me passaram credibilidade então não respondo mais a processos seletivos vindo dos mesmos

I appeared for the interview two times, for a business analyst role in POC/Catalog. I explained everything the interviewer asked. But in feedback, it was shared that I don't know about the catalog. The funny part is I have worked more than 9 years in catalog. I was rejected only because of the insecurity the employees have in this company. The interviewer was senior to me, but seems I was earning more than him even in current company. Technical Interviewer asked me about my current salary and expected salary. I think this info should only be with HR and technical interviewer should not be involved in such questions.
