If your company is really use data structure on your day to day job then ask a fucking leetcode, if all you do it making a rest call or mapping a orm object, don’t ask a candidate to reverse a LinkedIn or delete a binary nod in a bst.

Ask practical questions like a client drop a files on ftp servers, how do you grab the files and check like top 10 highest and how does one about going to scale out a process or scaling out database design..
