Spire Anonymous interview questions

The interview process was terrible. Started out great, but when downhill after the initial contact. Applied and heard back within 1 week that info was sent to hiring department. From there it took approximately 5 to 6 weeks before I heard back from HR. Was invited to do a phone interview which went well due to getting an in person interview approx. 2 weeks later. After the in person interview it was about two months before I heard anything again. Followed up during the two month time period, but never received an email reply back from HR or the hiring manager. Very unprofessional. You cannot expect people to be professional with you and then not extend the same courtesy.
