Emilia Wickstead interview questions

I had a video call interview, which went great, spoke to two people part of the company who were very nice, great interview. I was asked to come into the offices for a trial afternoon which I happily accepted. The trail afternoon went great, everyone I met was really lovely and I was told I would hear back the following week. I heard nothing that week, I followed up and nothing. I followed up again and still nothing. I only got a reply two months after my trail afternoon. Very disappointing to never hear back, particularly after two interviews, one being a whole afternoon of work in person.
