Intuit SDE intern interview questions

Karat technical interview questions, one hour.

The interview consisted of 2 questions. 1st was easy and based on basic array operations. I was able to answer the first one instantly. The second one was difficult and the task was to create a data structure using any other data structure(s) such that all operations, insertion at index, deletion at index and deletion of specific number is in O(1). I was able to discuss the problem using hashing but was not able to give the final solution. I was not selected for further rounds.
