McKesson Corporate Strategy interview questions

Very unprofessional interview process. Screening call with interviewer which was great. Interviewer asked me when I could do a follow up interview and I told him some times and he said he would get back to me. I never heard anything back and I had to check the website to see I was no longer under consideration. I was really looking forward to moving forward with the company and it was disappointing they didn't even email me to let me know. They called me for another role and asked to schedule an interview then went dark again. Had to check the website to see I was no longer under consideration.
