Interesting. Given the source, the conclusion was probably already determined when they set up the study.
In fact, some years ago there was a study that showed the opposite: Putting your religious affiliation on a resume actually hurt your chances, unless you were Jewish. And this study was conducted in the Deep South, where people are overwhelmingly Christian.
The study of religious discrimination in hiring recently published in the journal Social Currents found job applicants whose résumés betrayed a religious affiliation were 26 percent less likely to be contacted by an employer — except for Jewish applicants.
Employers preferred the control group. This confirmed the researchers’ hypothesis that employers would be put off by overt statements of religious identity. Even in the South, which is more religious than any other part of the country, it’s possible that employers would view overt religious expression as potentially offensive to clients and co-workers.
“Only Jews escaped totally unscathed,” researchers said, reporting “no statistically significant evidence of discrimination against this group across all eight indicators in the study.” In fact, researchers found that some employers seemed to favor Jewish applicants, as they were more likely than any other religious group to get an early or exclusive response from an employer.
As for Israeli names, well foreign names in general tend to get fewer call-backs. I suppose if you put a fully Slavic sounding name like Piotr Czerwinski, or a Spanish name, like Pedro Gonzales you'd see different results because they assume you need to be sponsored to stay in the States. I have had Ukrainian friends who actually got caught up in some of the Anti-Russian sentiment, and because their name sounded vaguely "Russian" to ignorant people
I'm guessing that they basically see Jewish people as more or less white people with a slightly different religion (even if some Jews would insist they're a separate group). Sure, if a guy walks in with a black suit and a big fur hat it turns heads, but most Jewish people don't actually wear that.
