Parks Project interview questions

Do not start working for this company! It has so many red flags...I had two zoom interviews and was invited to their on site office to have a presentation regarding sales strategies and then I was offered the job. Two days later they call me to let me know they withdrew the job offer telling me they didn't have the budget and doing some structural changes in the organization. The day after I see the position I was offered is posted on LinkedIn again.. They left me with so many unanswered questions and seem very unprofessional.
