Stripe Software Engineer Interview Experience — Three Parts of a KYC Validation Problem

KYC, but verifying things like the company name, URL, abbreviation, and description. The first part was to check whether there was a business name. Skip entries without one. For entries with a name, check whether the remaining columns all have values. If they do, it's verified; otherwise, not verified. The output is verified/not verified and the name, one line at a time in input order. The second part checked two fields. One had a length limit of 5–32 characters, including spaces. The description field had to be checked for keywords, including words and phrases. I initially used str in str directly to get it implemented quickly. If a keyword was present, it was not verified. The third part checked whether at least half the words in the name appeared in another field, something like a nickname. If fewer than half appeared, it was not verified. Suffixes like LLC and Inc. were ignored. I ran out of time and didn't see the fourth part.
