Thanks, I was not going to accept your offer, because I already accepted. I have some feedback for you, though you didn't provide anything for me: However, I am really surprised as to what could have gone wrong in the interview, when 4/5 people said yes, and the 5th person was however not able to solve the question by herself. Firstly, I think you guys need to recheck whether your internal engineers even know coding, before they start interviewing others(maybe try out some Udemy courses) Secondly, I think you guys should recheck your beliefs of a Data Engineer. They are NOT DEVELOPERS! Thanks good luck
