It was a single 45-min online interview. One round of Leetcode questions for about 30 minutes to solve, the interviewer first asked me to merge two sorted lists into one sorted list. The coding platform was somewhat like notepad which you cannot run the code and can just write code. After I came up with the solution, the followup question was to sort k sorted lists into a single sorted list. I wasn't able to fully code the answer but was able to come up with time complexity and space complexity. Next were 15-minute Leadership principle questions. I got 3 questions, which you can easily find if you search.
