Sustain.Life interview questions

The process was long the first time I interviewed. I asked to remain in contact, met with the director and when a position opened up they said I would be considered. I then had to meet with 4 more people before what was said to be a presentation round. I had so miss an interview due to a client escalation, gave ample notice and was met with “we will reschedule.” The client offered to be a reference for me as well so added bonus! The team was meeting in person and then without an explanation at all it went from we will reschedule to we hired someone else. Transparency was clearly not a great as they led on which is unfortunate. Though this time around HR was less involved which may have been the issue.
