I work in post-sec education and deal with a lot of immigrants and ESL (English as Second Language) people. I'd caution not to be too hasty on the spelling. Could be this person is fluent in five languages and English is not their first language. Could be she is still a very intelligent and fascinating individual.

Another case in point - I enjoyed the benefit of a man who mentored me for many years who was incredibly brilliant, but his spelling and grammar were atrocious. He more than made up for it in his ability to apply critical thinking skills, strategic planning, and leadership. He is still my "go to" person even though I've now surpassed him in my field. I used to be a stickler for spelling and grammar (it used to literally hurt my eyes to see things spelled incorrectly). Now, I focus on the message being sent more than the spelling of it.
