For me the interviewer started asking questions based on my projects , which was a E-commerce website . How I designed the database and why no-sql database , differnt api's that i created , collections , also he was giving some functional requirements and based on that how i will change my api . The project discussion went for about 30 mins and after that he gave me a question based on linked list that i solved and explained it using different methods.
Some of them are :

They were looking for candidate's logical thinking process that wheather he/she can identify a problem and try to solve them and know the basics of system design . They will pick your one project and then the whole interview will be based on that project and how you will make changes to scale that project . The interviewer picked my project on online assessment platform , asked about database design , also added some new functionalities and based on that how and what changes i will make in database. How i wiil scale the servers for millions of users .
The interviewer was happy with performance and also gave me a feedback to work on my system design basics .
As it was a new round for me i only watched system design videos on e-commerce and on some basics system design concepts .
