Expedia Group interview questions

I had a phone interview with the hiring manager which went well and there was an understanding that I was the person they needed. Then followed an on-site interview which was less favourable. I felt lured in for interviews when I wasn't the person they were really looking for. This annoys me with a lot of companies. Why do I have to take time off work and prepare for an interview when my skills don't exactly match what they are looking for at the moment? I wish they would stop doing this. It leaves a bad impression of the company, especially when they don't thoroughly explain their decision afterwards or are too cowardly to even call you.

Took almost 3 months from start to finish. interview day was long, no breaks given and people were back to back x 6. Then took almost a month to be told no offer. Was told a few times they haven't decided yet, Granted it was over the holiday season but they just didn't seem like they had their act together.
