Crunchtime interview questions

Got to the third round interview which was a task interview. Spent about a week preparing for it, then the day of the interview I get a call saying the position has closed. Extremely unprofessional and a waste of my time.

I applied through there website and got contacted about 4 days later (counting the weekend days). I received an invitation to schedule a meeting on a website but the actual interview is through zoom. Once I had the interview, the recruiter said I would know within the next day if I would move on. The recruiter didn't seem too comfortable with her role. She said she would put my information in the system so maybe that meant for a denial. I received the denial two days later despite having experience in implementation and experience with software configuration as mentioned in their ad. -_- Their loss. (Also the expected budget for this position starts at 60k)
