Problem statement

Validate each business account using the first three KYC checks reported by the interview author.

Input

csvData contains a header followed by business rows. Each row has these six comma-separated fields in order:

  1. business_name
  2. business_profile_name
  3. full_statement_descriptor
  4. short_statement_descriptor
  5. url
  6. product_description

Trim surrounding whitespace from every field.

Verification rules

  1. All six fields must be present and non-empty.
  2. full_statement_descriptor must contain between 5 and 31 characters inclusive after trimming.
  3. The full descriptor must not equal any of these generic descriptors, compared case-insensitively: ONLINE STORE, ECOMMERCE, RETAIL, SHOP, GENERAL MERCHANDISE.

Return one result per business in input order: "VERIFIED: <business_name>" when every rule passes, otherwise "NOT VERIFIED: <business_name>".

Function

validateBusinesses(csvData: String) → String[]

Examples

Example 1

csvData = "business_name,business_profile_name,full_statement_descriptor,short_statement_descriptor,url,product_description\nPawsome Pets Inc.,Pawsome Pets,PAWSOME PETS,Pawsome,pawsome.example,Pet supplies\nBean Bliss Coffee Company,Bean Bliss,,Bean,bean.example,Coffee beans\nGlobal Goods Marketplace Inc.,Global Goods,RETAIL,Global,goods.example,General products"return = ["VERIFIED: Pawsome Pets Inc.", "NOT VERIFIED: Bean Bliss Coffee Company", "NOT VERIFIED: Global Goods Marketplace Inc."]
Pawsome passes all three parts. Bean Bliss has an empty full descriptor. Global Goods uses the exact blocked descriptor RETAIL.

Example 2

csvData = "business_name,business_profile_name,full_statement_descriptor,short_statement_descriptor,url,product_description\nInformation Technology Consulting Solutions Inc.,ITCS,ITCS,ITCS,itcs.example,Consulting\nOm Yoga and Wellness Center,Om Yoga,OM YOGA AND WELLNESS,Om Yoga,omyoga.example,Yoga classes"return = ["NOT VERIFIED: Information Technology Consulting Solutions Inc.", "VERIFIED: Om Yoga and Wellness Center"]
ITCS is only four characters, below the inclusive minimum of five. Om Yoga supplies every field, has a valid descriptor length, and does not use a blocked descriptor.

Constraints

  • The first line is a header and is not validated.
  • Each data row is a simple six-field CSV row with no embedded commas.
  • All fields are trimmed; an empty trimmed value fails verification.
  • The full descriptor length is inclusive in [5, 31].
  • Blocked descriptors use case-insensitive exact equality, not substring matching.
  • Return results in input order.
