I met with someone from HR who was prescreening. I thought I did quite well, but I think the culture is very young at this company. As I am not in my 20s or 30s anymore, I guess she felt I would not be a good fit?

The interview process was very long. The talent aqusition team where professional and kept touching base every month or so. Saying that if you are serious about a position the process should't take more than a month or so. mine took 4 months.
