Interview starts with 2 default leetcode tasks,such as merging two sorted linked lists into one,or maximum consecutive ones. Usually it is about checking how clean,and how bugproof your code really is,rather than coming up with a solution

The interview lasts 1 hour. You get 2 algorithmic problems - simple and medium in complexity, and you need to write a solution without bugs. The interviewer can give you a hint if you need it.
