I was given a java code in which I had a list of products (product names may contain more than 1 word), when user searches for keyword (say Chocolate Milk) then all the products having either of those two words need to be returned regardless of the order of the words in keyword. I also has to write unit test for my code

introduction with in house recruiter, then technical discussion with software engineer about my technical background, followed by code pairing and system design with engineers and finally a behavioral interview with product.
