Granicus interview questions

The process was as follows: HR interview, meeting with team, unpaid work test, then final interview. The process is long and a bit dragged out but everyone seemed nice. The advertised salary wasn’t the best either.

I was solicited to apply by a Granicus HR person via email. After going over the job description, I was sent their calendar to pick a day and time for the first interview. On that day that person called 10 minutes late. When I picked up the phone there was no one on the other end. Then 4 more calls right after form the same number and the same thing: No one there. So I tried to call back but it was a general "front desk" number. I tried every deptartment in their phone tree to get me to a live person and absolutely no one picked up phone in this company.- Not even in the sales department. A few minutes later I got an email from the HR person saying they treid to reach me but could not and asked if the phone number was correct. I replied that it was and that no one was on their end of the phone when I answered. I further explained that I tried to call her back but nobody picks up the phone at her company and aask her for a number that I could call her back on. That was the last I heard from her in that email. No reply. No offer to reschedule, Nothing! I figured this would not be a company I would want to work for if they treat you like this BEFORE you are an employee. Plus what company does not pick their sales line???
