Secretariat interview questions

The interview process was pretty tedious and seemed a little bit disorganized...I had 4 different interviews (all virtual) over the course of about a month. I would have rather had it all in one day. The first interview was the basic first round with HR, followed by an interview with an associate, then manager, then director. Most of the questions were basic, asking me to give specific examples situations in which I had to apply a certain skill. I was very frustrated as I was ghosted by the company after interviewing... I sent a follow up message a few weeks after my final interview and never ended up hearing back. I felt this was extremely rude and unprofessional, considering I had been interviewing with them for over a month.
