I had a quick call with HR and was then invited to the second round which was interviewing two senior frontend engineers for two hours. The first hour was the System design question which is something not that practical if you ask me but it opens the door for more questions so there is no right/wrong answer here and you can't be sure if you are doing good or not. Also some react question has been asked , they are pretty generic but they are trying to get the answer that they want from you , they are also helpful and try to help you to get the answer that they are looking for, Second part is writing really simple app with react in stackblits website and you need to share your screen and also you can search. try to make this part as perfect as possible from my understanding they are really specific regarding what you write and not that interested in just solving it and then polishing it. In my experience, they took their sweet time to give back to you.
