Overall schedule for the second round of applications
Do you have this problem?
I don't know which application category is best suited for my company. There are so many categories—conventional, manufacturer-reinforced, top-performance, etc.—that it's hard to decide.
The application forms are enormous, and I'm too busy with my main job to handle them all. I want to delegate schedule management so I can focus on my core work without being overwhelmed by the sheer volume of paperwork.
I want it to be accepted, but I'm afraid of being rejected due to a mistake. I want to avoid the risk of being disqualified from the review process due to minor document errors or calculation mistakes.
