In L1->4 sum array question arr=[2,4,3,5,6,1,0] target=10 something like this. In L2-> asked to right a user auth api and use it in the endpoint (i used Depends from fastAPI) and another coding question was about parenthesis match is_valid_parenthesis([({})]) #TRUE. React question- useLayoutEffect vs useEffect, useMemo, useCallback. js- output based js question related to event loop priority like promise vs setTimeout vs console.log use chatGPT it will give you the exact question.
