This person is bi-lingual, and I'm suspecting that his/her first language is not English. If the word were spelled wrong once, you could say it was a typo, and fault him/her for failure to pay attention to details (vital skill in food prep). But the error was consistant throughout, in each place where the word was supposed to be "cook or cooking".
There are more errors than just the ones circled. I'd guess it's a semi-literate English speaker. My posts here aren't perfect, but on a resume I'd do better than that! Funny stuff there, but I wouldn't count the applicant out just for that. My 2 cents.
Do any of you know an adult with a learning disability? That's another possibility. I'm a retired special education teacher (and reading specialist), and that's what I'd think of first.
Just for the record, people with LD don't necessarily have reduced intelligence. Spelling is a common area for LD.
Finally, if I were an adult with LD and was submitting a resume, I'd have someone else proof read it. LD is an explanation for having difficulty, but not an excuse for not bothering to do what you can to get things right.
