DreamBox Learning Sales interview questions

Went through an initial phone interview then had a virtual interview where I was told I would be moving on to the next stage of interviews. Several days passed before I reached out to HR POC regarding the follow up interview. A few days later I received a reply and the interview was scheduled. 15 minutes prior to the interview I was informed the interviewer was no longer available at this time and to please provide upcoming dates of availability, which I did. Several more days pass still with no reply to my dates of availability sent to HR contact. I reach out again. Several more days pass during which I receive an offer from another company. I informed the HR POC that I had received another offer and that I really did not appreciate the lack of value and courtesy shown to me as a candidate and with respect to my time. I never received an email response, no 'wish you the best' or 'thanks for your feedback, sorry you didnt have a good experience'. Nothing. Happy to be with a company whose culture values people.
