Avicado Construction Technology Services interview questions

The interview process looks as follows: 1. Screening call with Talent Acquisition 2. 1-Hour call with Director 3. 2nd 1-hour call with the same Director 4. 1-hour call with Managing Consultant 5. Well I was slotted for a 5th call but saw an hour and a half before it was scheduled that it was canceled, then subsequently received a very generic denial email from a no-reply@ email address. After reaching out for feedback, I have received no response from those previously contacted/interviewed. Neutral review strictly on the handling of the denial, but overall positive conversations and people. After 3 interviews, give a more personalized email, after 4 give someone a call.
