Following two rumors prevail in students under job-hunting.
・Those who have belonged to sports clubs are favored by recruiters
・Those who are railfan are not acceptable for recruiters
These rumors are assigned to conventional orders.
To be more specific, newly hired workers are required to obey their senior workers absolutely (even when senior researchers order them unreasonable task)
In such a situation, workers who experienced senior students' unreasonable order in sports clubs are supposed to take proper measures.
On the other hand, railfan, which can be in good terms with other railfan regardless of age, are supposed to be unsuitable in such a situation.
The convention seems to be the obstacle of job-hunting.
