My senior researcher who is in job hunting said to me "I got the mail about the date of the company guidance. Then, I clicked the link in the mail only to find it full. But, I noticed that it was strange that the reservation was full, despite that I checked the mail 5 seconds after receiving it.
I tried changing my academic career written in my profile into Kyoto University. After changing, I clicked the link again. To my surprising, there are vacant seats in the company guidance."
We can definitely say that the company sets "academic filter" to rule out applicants who have poor academic careers.
