According to a Spanish newspaper, women hoping to become flight attendants with Kuwait Airways were told to take off their underwear in order to be inspected.
A female recruit wrote in a notebook that she felt like an animal when she was asked to strip to her bra, skirt, and pantyhose.
Meccti, the world's largest cabin crew recruitment agency, held a recruitment event at a hotel in Madrid, Spain, in November.
The interview process was not comfortable from the beginning, according to three sources.
Recruiters turned away women with glasses, braces, visible scars or moles, as well as any they judged to be overweight, when they first inspected them, according to sources.
Some people were asked if they would be willing to lose weight, while other people were asked if they would be willing to eat more.
Recruiters said they didn't like her skin or her smile and rejected her.
According to El Diario, three of the 60 or so people at the event were male, but they were turned away after being told that the airline only hires men from Kuwait.
Shortlisted candidates were asked to undress by a female scrutineer.
The first girl to go in came out crying, according to Bianca.
She told the other candidates that she had been ordered to take off her clothes. The other people said the same thing. I couldn't believe it. Bianca told El Diario that she was freaked out but they were not exaggerating.
The female recruiters asked Bianca to pull up her dress. Bianca said that she pulled it up to her underwear. She asked me to pull my dress down to my waist because it had a zip down the back.
Bianca was told by the recruiters that she was looking for cars, birthmarks and tattoos.
Mara said that first she took off her blouse and then left her pants on.
Mara told El Diario that he was looked at from the bottom up.
Candidates need to be at least 5 feet, 2 inches with their "weight and height in proportion" and have an "excellent overall presentation" according to the advert.
Spain's Department of Labor is investigating Meccti's hiring practices. The labor minister described the conduct of the recruiters as intolerable.
