Got the call from HR to schedule interview. He told that 1st round is going to be tech round which would consist of DS problems. Instead my interview started with theoretical flutter questions. Most of them were simple straight questions. But few were like what is flutter framework architecture. Like why would anyone would be interested to know that. No practical problem on flutter related to list view builder, statfull, stateless widgets. Complete theoretical book questions. Only one problem asked in the end, to find the random number involving just arithmetic operations. And you cant take global variables.
