No need to be "desperate". I have a few friends that interviewed with a lot of companies before getting their job. There are quite a few people here at XJT that got turned down the first time and than offered a job on their second interview. If you want to really work here than keep applying and keep flying and gaining experience. I know multi time is hard to come by so keep trying to get some more of that. Who knows why a company hires or doesn't hire sometimes. Keep trying and you will be at an airline soon. Then you can start wish for other other things like more days off and better pay.
Good luck.
