Hilton ECommerce Manager interview questions

August 18- Submitted my resume to Hilton Worldwide August 20- Receive an email from a "Client Recruitment Specialist" asking for my availability for a phone interview. I reply within an hour with times over the next couple days. August 21- Over 24 hours have passed since I sent my availability reply to the recruiter. I haven't gotten a reply yet. I send a follow-up email to her. August 22- She finally replies back in the morning saying she'll call me at 1:30. 1:30 comes, 1:30 goes. I get no call. I send an email to her asking if we should reschedule. August 26- She sends me another email asking what my availability is for that week. I reply. August 29- Still haven't heard back. I send another followup email. She never replies. The whole process was surprisingly unprofessional for such a large international company. The recruiter's actions showed little respect for my time and effort.
