Super unprofessional. Don't try to go to their interview at this time of pandemic. They will take you for granted.
I applied for this position through their website, and I got invitation for an interview. But when I got I there, I was so disappointed for them to tell me that there is no available position for the job, and offered me a lower position. I declined the offer, because of course, those positions are way too out of my expertise and the degree I finished. They are very unprofessional! Especially without considering that we are still in pandemic, and the difficulty in commuting to their headquarters are way too high.
Hope this will get to the HR itself. You need improvement for your hiring process
