PayPal Software Development Engineer In Test SDET interview questions

My interview process was slow and unprofessional. It took a month without a final round since I applied. Especially once I got the first round interview, I was told that I was selected for final round and gave them my availability. I did not get any update, it should not be a big deal to schedule an interview with interviews. While waiting for the final round, I was told that position was internally filled. I have no problem with that position is internally filled. But it is not nice to hear that after getting all steps done. Additionally, I got an email which says I did not show up in the interview that I did not get the invite for. The result is that I got only first round and while waiting for final round , I learned that the position filled internally. And all of these took a month. As I said, I did not get even final round. I wish the process was not that much slow. I already got 3 offers within same time frame and I am sure I will also have a wonderful interview with PayPal. I just prioritized PayPal most since it is PayPal.
