Welding Tips and Tricks

I completed school back in 2016 with my basic and advanced SMAW and GMAW certicate of completion. I had trouble finding a welding job due to lack of experience, so I took a job at a sawmill and have worked my way up to sawyer. I have done a little "bush" welding to help out maintenance over the years but really want weld full time. I have an opportunity for a production welding position at a heavy equipment company. I'm not sure what to expect for testing and to be completely honest I'm doubting I would pass during to how long its been and my lack of experience. Any advice on how to prepare and what yo expect would be greatly appreciated.
