PTC interview questions

1/2 hour phone interview, followed by 2 hour in person interview. After the in person interview, the HR person sent an email and said they though everything was positive, but they decided to go in a different direction. I did not reply, nor ask what that exactly meant. A day later, one of my co-workers get a Linked-in email, trolling for someone to respond. I suspect it was because their salary is low and they are looking to get someone more junior. If it's not a "Senior" position, then don't waste interviewees times...I was annoyed. Hence, I would not work here. I've seen other postings from the for "Senior" positions, but in the end what they are looking for is college grads.
