data engineer interview questions shared by candidates
SoftDev : Python (I chose), you have an array of string sorted but with empty strings (e.g. ["abc","","","","cef","","","dej,""] and you want to know if an other string is in this array. How to do it with a complexity of O(log n) in general case ? Then how to find how many times it appears in this array ?
US director joined and some questions about work and few basic questions on SQL queries. And one more person will popup start interview which was totally surprising me as I was not aware .. Once I finished with that Guy then another person popup and took interview .. All seems well and at last no clear feedback by company since two weeks.
