Extremely poor candidate experience from recruiter. Only form of communication was via email in which the candidate needs to initiate: Interviewers very friendly and outgoing Recruitment turned me off moving forward

I got a message from a Microsoft recruiter that the executive saw my profile on LinkedIn and wanted to talk. I applied online and filled out more information via email. They wanted me to talk to the hiring manager the next day, which I did and she wanted me to talk to the executive the following day. I then received an email to do 4 additional interviews, 3.5 hours. I gave them my availability and they totally ignored my dates I had sent and I had to scramble and rearrange my schedule to make it work since they were moving quickly. I then received an email from the recruiter an hour before my interview loop on interviewing tips and advice, clearly not helpful at this point. I let the recruiter know at the end that I would be on vacation for the next week but will look forward to hearing an update when I return. Two weeks go by and I get an automated email saying they won’t be moving forward with me. From the moment the recruiter messaged me to the last interview, this was a matter of a week of communication. I change my schedule around and was flexible to accommodate, I would expect a personalized email update or a phone call to let me know I didn’t get the job. Besides the interviewing process, I had great conversations with everyone so it was disappointing it ended this way. Such a sloppy process from such a renowned company.
