CA Technologies Customer Success Manager interview questions

After 4 rounds of interviews where all involved parties assured me they had approval to continue hiring despite being acquired by Broadcom, I was looking forward to a final in person interview. Nearly a week after my 4th interview, the recruiter emails me saying the position has been cancelled due to the acquisition. Clearly, they have no idea what is happening and should stop interviewing hopeful candidates until they can determine the road map and future of the company.
