Knighted Ventures interview questions

I was contacted for a phone interview and then a video call interview in spring. I moved onto the in person/video call panel interview and it went well. Unfortunately this was during the beginnings of the COVID-19 lockdown, so the offices were closing and they told me that they would put my application on pause and schedule a final interview once a better time-frame was given. They had also given me the talent acquisition manager's contact information for any questions, and told me she would be my new point contact forwards on. I had called the manager for a question, and was left with no answer, and left a voicemail. The call was never returned. In June I called the manager again, and this time I was finally able to get a hold of her and asked her if there were any updates regarding the company and the HR Admin Assistant position. She told me to call her back the next week to schedule the last interview with a better time-frame. I've called and called, left voicemails and sent emails within the next three weeks, with no response. I was basically ghosted. I understand that the pandemic is hindering companies and its employees, but it would be wise to at least call back and contact candidates whether or not if they are moving into the next hiring stage.
