Deloitte Scrum Master interview questions

The HR recruiter reached out to schedule an initial phone screen. The availability I provided her had to change since she took 2 days to get back to me. I immediately informed of the desire to reschedule due to a meeting conflict I couldn't shift. No response. Followed-up again the next day, she said she'll reschedule. No response. Followed up one more time, never heard back from her. This gave me a bad taste for Deloitte. All employees represent the company image, the HR recruiter did a poor job.
