Halodoc Software Development Engineer In Test II interview questions

First Round - DSA : Had to share my screen and write the code in note pad. The interviewer was helping. I have given the questions below. This round was pretty much easy. Second Round - Selenium Automation: Given a bus booking site and a scenario, i had to automate it. All the tools should be ready to use so that you can directly create a framework outline and start automating. The duration given was 2hours. It's a pretty easy one. However, i couldn't complete as it has been a while since I worked on selenium automation.
