75 data warehouse developer interview questions shared by candidates
I don't quite remember. It was a while ago. They had good relevant questions.
The behavioral, SQL, ETL, and coding questions asked during the phone interview were pretty basic. Onsite questions 1. Implement a trie (NOT tree) data structure with insert, search, and startsWith methods. 2. Given an array of strings, group anagrams together. For example, given: ["eat", "tea", "tan", "ate", "nat", "bat"], Return: [ ["ate", "eat","tea"], ["nat","tan"], ["bat"] ]
They use canned interview questions about experience, and skill familiarity.
