Fervo Energy interview questions

I had applied previously, was very interested in the company. New posting came up and they reached out to me. Phone call with HR went fine. Everyone seemed excited and a checked evey box. Virtual interview with hiring manager, went great it seemed and told me they would be at a offsite the following week but would get back to me the week following. Multiple emails following with "yes, we'll get back to you next week". Never heard, emailed hiring manager, no response. To this day, I have not heard anything and was just ghosted. I was also told this happened to other colleagues of mine, one after 3 rounds and a panel case study presentation. After this experience I would never consider working for such an unprofessional company.

The first round will be conducted as a video interview with five questions. Before answering each question, you will have 1 minute to prepare your response, followed by 1.5 minutes to record your answer.
