I was contacted to arrange a phone interview on a Friday afternoon. After responding on that evening, outlining the times I was available the following week given I am currently employed, I received an e-mail on the Monday morning, requesting I be available 20 minutes later for a call. This came after I identified Monday as a day where I was not available in my initial response. I followed up with the recruiter after work that evening, again identifying dates and times where I was available, and never heard back.
