Meta Recruiter interview questions

I was contacted via a Linkedin inmail for a Recruiting position at Facebook. The first inmail came on Nov. 7, 2017. I responded back via Linkedin and email on Nov. 10 to set up a call with the Recruiter. She responded pretty immediately setting up a call for a few business days from our email exchange. After never calling me, I followed up with her via email again. She was out of the country and asked to schedule when she returned a week or so later. I will give her credit for reaching out after her return, but it was at least 2 weeks later bc she said she had gotten sick after returning from the vacation. At that time she looked to reschedule the call with me. I responded to her with available days and times and never heard back. Over a 4-5 week period, I was strung along which didn't so much bother me as a person since I wasn't an active job seeker and very much enjoy what I do with my current employer, BUT as a professional in the field it very much bothered me as you would expect a brand like this to offer great candidate experience, including their sourcing and recruiting process.
