Let's say I work for a company called BobSoft, they're a consulting company with a contract with CharlieSoft.
BobSoft is sending me to a training class out of state in about 5 weeks, but I see that CharlieSoft has a position open doing work somewhat similar to what I'm doing now. I'd like to apply for this position since the salary and benefits will be a lot nicer.
In the job description for the position at CharlieSoft, they said that conference attendance is encouraged and they will pay for it, and said that I will be traveling 25% of the time. It is somewhat likely that if I were to already have this job, they'd be sending it to me anyways.
BobSoft has already paid for the class, though they can get a refund. However, my flight has already been purchased and is not refundable. When in the application process should I mention this class to CharlieSoft? In the cover letter? At the job interview? When they give me an offer? Or even wait until my first day with them? All assuming I get the job, of course. And then, how should I phrase it?
