Microsoft UX Designer interview questions

I interviewed with the Sr. UX Designer in November on the phone. A month later, I get an email from the recruiter saying that they have decided to move me to the next round, but it won't be until February or March since there are multiple openings and candidates being considered for this role. I waited until February, and then tried calling and emailing the recruiter to schedule the next round. But I could not get in touch with her, and in April I received an email saying that I have been rejected from the phone interview. Very disrespectful of them to do this.
