Cboe Director interview questions

Had a few formal interviews which went well but now it has been 7 weeks with no communication from Hr or anyone . Despite chasing in email and calling . It is extremely disappointing that there is this lack of follow up. This was for a senior role and expect a level of professionalism . To get a brief email or call As a courtesy is all that is needed . It is very rude and if they treated clients like that would not be in business .
