They've a job opening and they want a candidate to be present at the interview. However, while asking about salary range before going to the interview (as it costs a candidate), they're not professional to share even a salary range and the guy on call BLUNTLY refused to understand the query and said that if you want to come then come.
What kind of HR or recruitment skill is this?
Also, why so hesitant to share the salary range if you want to offer a good package?
Beware of the suspense!
