It is not just non-vet, but company quietly filters out people by marital status, age, ethnic/nationality, previous work, etc.

why is it not illegal? Let's see some example.

ethnic/nationality-
EXAMPLE (MADE UP)
ba&f, D@imler,B@ayer - "person who can speak German fluently. who can understand slang, and business and engineering terminology"
&@msung- "person who can speak Korean fluently, incl. business and engineering, telecomm terminology"
Ren@ult- same shit
NTT D0c0m0- same
&ant@nder- same

Age-
"Oh, you speak French fluently? How many years did you study French? Your accent sounds like you learned it from France"
After telling the interviewer how many years they live in France as a brag.
"How long have you speak English?"

You just gave out the estimate age


marital status-
Ring, get suckered in by talking about kid from looking at interviewer's family photo with special occasions.


Some companies asks illegal questions directly. Age. One of the most odd question was
"We require our employees to take the clients out to dinner/drinks. What is your tolerance level on drinking?"

After I got the job there, I drank so much that I had more than 10 gout attack.....
