L'Oréal Engineer interview questions

Started with a phone screen with external recruiter, followed by a phone interview with the hiring/engineering manager. Final phone interview was with both a second engineering manager and the engineering director. One face to face interview for a half day with 3 engineers, 2 engineering managers, and the engineering director, plus HR for you to ask any HR related questions. I was applying from out of state, during the entire process they continued to remind me there was no budget for relocation, which I was ok with given a reasonable offer. Before each phone interview this was brought up. When it was time for a face-to-face interview, they were reluctant to fly me out there -they wanted to be certain I would accept an offer if one was given. Without an offer on the table, I couldn't make that promise. Luckily, I was able to make arrangements so it wouldn't cost them anything for me to come out there -but it required vacation time and money on my part. After the interview, that I thought went generally well, I was told they decided they wanted to pursue candidates with less experience and lower salary requirements (which I made clear from the first phone screen). I'm not bitter because I didn't get an offer. I accepted a more interesting opportunity elsewhere in the Seattle area -so offer or not I probably wouldn't have ended up working here. But I am pretty annoyed that during the entire process they continually wanted to make sure I was serious about working there, when in the end (after time and money out of my pocket), they apparently had no idea what kind of candidate they wanted to hire.
