The phone interview lasted exactly 45 minutes. The interviewer started asking algorithm questions without any self-introduction. You may need to practice writing code using an online editor. You may need to provide test cases yourself and explain them to the interviewer.

The first question was to merge two sorted array lists into one single sorted list.

The second question was to be given a list of tasks and return the minimum time needed to finish all tasks (like task-scheduler). The only difference is that the original positions of tasks remain the same.
