Discover Communications/Engagement Manager interview questions

Very disrespectful experience. I was invited to an interview with HR. At the scheduled time, the HR person didn't call me. I waited for 15 minutes and then I called her. Voicemail. I e-mailed her (three times and I didn't hear anything back). If this is the way they treat candidates during the HIRING process, can you imagine how is the work environment? Suggestion: there is a very nice page on the company's website with interview tips. Delete it. HR is not doing its job.
